Enzymes
Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food, for stimulating the brain, for providing cellular energy, and for repairing all tissues, organs, and cells.
There are three types of enzymes: metabolic enzymes, digestive enzymes, and food enzymes.
Metabolic enzymes catalyse, or spark, the reactions within the cells. The body's organs, tissues and cells are run by metabolic enzymes. Without them our bodies would not work. Among their chores are helping to turn phosphorus into bone, attaching iron to our red blood cells, healing wounds, thinking, and making a heart beat.
Digestive enzymes break down foods, allowing their nutrients to be absorbed into the bloodstream and used in body functions. Digestive enzymes ensure that we get the greatest possible nutritional value from foods.
Food enzymes are enzymes supplied to us through the foods we eat. Nature has placed them there to aid in our digestion of foods. This way, we do not use as many of the body's "in-house" enzymes in the digestive process.
This is important to remember.
A present theory is that humans are given a limited supply of enzyme energy at birth, and that it is up to us to replenish our supply of enzymes to ensure that their vital jobs get done. If we don't replenish our supply, we run the risk of ill health.
There is a that theory mentions that the length of life is inversely proportional to the rate of exhaustion of the enzyme potential of an organism. The increased use of food enzymes promotes a decreased rate of exhaustion of the enzyme potential."
In other words, the more food enzymes you get, the longer, and healthier, you live.
As food enzymes are destroyed at temperatures above 118 F processed foods contain few, if any enzymes, and that the typical diet is enzyme-deficient. When we eat this type of diet, we could well be eating for a shorter and less-than-healthy life.
This shows the importance of eating raw fruits and vegetables because they are "live foods"; that is, foods in which the enzymes are active. The more enzymes you get, the healthier you are. And the more raw foods you eat, the more enzymes you get.
Enzymes carry out the role of detoxification -- breaking down toxic substances so that they are excreted and cannot build up to possibly cause harm. Although this is done by metabolic enzymes, research shows that enzymes found in the foods that we eat, although not food enzymes -- may help our bodies do this.
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
Chapter one of Catching Fire is an explanation of the Raw-Food diet that has become popular in recent years. The author chooses first to explore the history of raw food, then share with the reader the raw-food experiment
Digestion have a function of breaking down all food into our body. Our body use all nutrients to help in the process been health and growth. Digestion supplied small molecules that will be absorbed into our bloodstream.
Enzymes are types of proteins that work as a substance to help speed up a chemical reaction (Madar & Windelspecht, 104). There are three factors that help enzyme activity increase in speed. The three factors that speed up the activity of enzymes are concentration, an increase in temperature, and a preferred pH environment. Whether or not the reaction continues to move forward is not up to the enzyme, instead the reaction is dependent on a reaction’s free energy. These enzymatic reactions have reactants referred to as substrates. Enzymes do much more than create substrates; enzymes actually work with the substrate in a reaction (Madar &Windelspecht, 106). For reactions in a cell it is important that a specific enzyme is present during the process. For example, lactase must be able to collaborate with lactose in order to break it down (Madar & Windelspecht, 105).

The function of the digestive system in the human body is to break down macromolecules into their individual monomers so the body can process them. There are two major types of digestion that occur in the body. These are mechanical digestion and chemical digestion. Mechanical digestion is the mechanical process of breaking down food particles into smaller pieces. Chemical digestion is the secretion of enzymes and chemicals that break down the food even further into their individual molecules. Some common enzymes in the human body are amylase, pepsin and lipase. Enzymes are catalysts that speed up reactions but aren’t reactants themselves. Different enzymes also react on different substrates, for example, amylase reacts on carboh...
The human digestion system is very complex. It starts with the mouth, salivary glands, pharynx, esophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine, then ends/exits with the anus. Each step is essential to the whole system. For example, the mouth chews food and mixes it with saliva produced by the salivary glands, and then the pharynx swallows chewed food mixed with saliva, this is followed by the food traveling through the esophagus to the stomach where the food gets a bath and mixes with acids and enzymes. After the stomach, the liver, pancreas, and gallbladder produce, stores, and releases bile and bicarbonates. Bile is produced in the liver and aids in digestion and absorption of fat while the gallbladder stores bile and releases it into the small intestine when needed. Following the process into the small intestine, this is where nutrients will be absorbed into the blood or lymph (most digestion occurs here). Next is the large intestine this is where water and some vitamins and minerals are absorbed. Finally, it is the end of the road, the anus. At...
The exocrine function of the pancreas is that it produces enzymes that aids in the digestion of food. There are three important enzymes that are crucial in helping with digestion. The first digestive enzyme is amylase. Amylase function is to break down carbohydrates. The amylase enzyme is made in two places: the cells in the digestive tract that produces saliva and the main one specifically found in the pancreas that are called the pancreatic amylase (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). The amylase in the pancreas passes through the pancreatic duct to the small intestines. This amylase in the pancreas completes the process of digestion of carbohydrates. Consequently, this leads to the production of glucose that gets absorbed into the bloodstream and gets carried throughout the body. The next enzyme that aids in digestion of food is protease. While amylase breaks down carbohydrates, protease breaks down protein. Protease breaks down protein into the building block form of amino acids. The three main proteases that it produces are: pepsin, trypsin and chymotrypsin (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). Pepsin does not occur in the pancreas but it is the catalysis in starting the digestion of proteins. Trypsin and chymotrypsin are the two proteases that occur in
Enzymes are necessary for life to exist the way it does. Enzymes help our bodies carry out chemical reactions at the correct speed. Catalase is one such enzyme, “Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals). It catalyzes the decomposition of hydrogen peroxide to water and oxygen”.\(Wikipedia). In other words catalase speeds up the breaking down of hydrogen peroxide, which is a byproduct of reactions in our body. Hydrogen peroxide is very common in our body but, “If it were allowed to build up it would kill us”(Matthey).This shows how necessary enzymes such as catalase to life. Without enzymes reactions that take place in our body could be affected greatly. In our
But is their scientific data to back this up? No, not really. It has been widely known and accepted that cooking our food is healthier and safer. Cooking foods kills any harmful bacteria, it lets us eat a wide variety of foods especially those who cannot tolerate raw uncooked vegetables, which can leave individuals with nutrient deficiencies. And well, yes cooking does kill the foods enzymes, our body has its own enzymes for proper digestion and health and doesn’t need other enzymes.
The function of the digestive system is to break down large food molecules, known as macromolecules, of carbohydrates, lipids and proteins into micro molecules that are small enough to be absorbed into the blood stream where the nutrients can be utilized by body cells. Food is not only broken down by chewing, which is a mechanical action, but by chemical action of digestive enzymes. Enzymes are large protein molecules produced by body cells. They are biological catalysts, which means they increase the rate of a chemical reaction without themselves becoming part of the product. As temperature increases, the rate of an enzyme-catalyzed reaction increases as well and works its best at around 37.5*C. However, very high temperatures denature enzymes
Enzymes are proteins that act as a catalyst to bring about a specific biochemical reaction. Enzymes contain an active site that allows the substrate to bind to the enzyme and form the enzyme substrate complex and then release the products. An enzymes main function is to increase the rate of chemical reactions. There are many different types of enzymes, each containing a specific set of optimal temperatures. These temperatures represent the set of conditions at which the enzyme works best in. Enzymes are used in our everyday lives in order to break things down, for example starch. Fungal and bacterial amylases are the two enzymes tested in this experiment to see their ability to break down starch. To determine how temperature affects
Without enzymes, reactions wouldn’t occur and living organisms would die. For instance, the enzyme in the stomach breaks down large molecules to smaller molecules to absorb nutrition faster. Researchers experimented with enzyme activity with a potato extract. Researchers will test enzyme activity by increasing and decreasing pH levels, lowering and increasing temperature, and substrate concentration effects. In the first experiment, researchers hypothesized whether different pH levels would change how much Benzoquinone are created and how will the enzymes function in neutral pH levels than higher and lower levels. Researchers used potato extract and different levels of pH to test their hypothesis. In addition, researchers questioned at what temperature does the greatest amount of potato extract enzyme activity take place in. Researchers then hypothesized that the results would indicate the greatest amount of potato enzyme activity level will take place in room temperature. In this experiment, researchers used potato extract and different temperature levels to test the hypothesis. Moreover, researchers wanted to test the color intensity scale and how specific catechol oxidase is for catechol. In this experiment, researchers used dH2O, catechol solution, hydroquinone, and potato extract. Lastly, researchers tested the substrate concentration and how it has an effect on enzyme activity. In this experiment researchers used different measurements of catechol and 1cm of potato extract. Researchers hypothesized that the increase o substrate would level out the enzyme activity
Food has been a common source of necessity in our everyday lives as humans. It helps gives us nutrition and energy to live throughout our life. Over several decades, the development of making foods has evolved. They have changed from natural to processed foods in recent years. Nowadays natural ingredients are barely used in the making of foods like bread, cheese, or yogurt. The food industry today has replaced natural food making with inorganic ingredients. The cause of this switch is due to processed foods being easier, cheaper and faster to make. Artificial nutrition and processed foods have been proven to last longer in market shelves then natural foods. Also, due to artificial additives in processed foods they help satisfy consumers taste more than natural ingredients. The method of producing processed foods is common in today's food industry and helps make money faster and efficiently for companies. Examples of this can be found in all markets that distribute food. Even though processed foods may be easier and faster to make, they are nowhere near as healthy for consumers compared to natural foods. Natural foods are healthier, wholesome, and beneficial to the human body and planet then processed foods.
Enzymes can be considered as the machines that carry out the majority of the chemical reactions that take place inside our body. These unique enzymes provide the work that is being done inside the cells. For over a century, scientist have been studying and experimenting with these proteins. Enzymes can be associated with a number of different things that take place in the body. For example, an enzyme can be the root to cancer cells. Researching about these highly chemically reactant enzymes has led to the discovery of a fairly new enzyme called Telomerase. Telomerase is an enzyme that is associated with the addition of nucleotides to telomerase (Yu-Sheng Cong). This enzyme is highly known for its activity with human cells, but most importantly,
