Introduction
Our bodies involve and require many different biochemical reactions, which is achieved through the help of enzymes. Enzymes are proteins in our bodies that act as catalyst as they speed up vital biochemical reactions by reducing the “activation energy” needed to get the reaction going. To sustain the biochemistry of life, enzymes maintain temperature inside our living cells balanced and the concentration of reaction molecules. Enzymes are extremely efficient because they remain remarkably unchanged, therefore have the potential to be used over and over again. They are extremely specific with the reactions they catalyze, like a lock and key and, extremely reactive. The molecule to which enzymes make accelerated changes to is the substrate. The molecule that is present after the enzyme-catalyzed reaction is the product. Most enzymes require specific environmental conditions such as temperature and pH levels to be met in order for them to function properly and efficiently. In the first part of the lab we specifically examined a simple enzyme-catalyzed reaction using catechol (the substrate) which will be catalyzed by the enzyme catecholase and will then result in color change. This familiar color

This hypothesis was also based on the results we gathered on Table 1. Our results showed that if there is a high level of acidity, then it would take a very long time for the browning to show. The banana slices #5 and #6 showed us enzymes under two very different pH levels. We added distilled water on to banana slice #5, this puts the enzymes under a pH level of 7 which is a neutral pH. On the other hand we added lemon juice to banana slice #6, this put the enzymes to work under a pH of 4 which is an acidic pH. We noticed that slice#5 browned a lot faster than Slice #6, because it was less
Living organisms undergo chemical reactions with the help of unique proteins known as enzymes. Enzymes significantly assist in these processes by accelerating the rate of reaction in order to maintain life in the organism. Without enzymes, an organism would not be able to survive as long, because its chemical reactions would be too slow to prolong life. The properties and functions of enzymes during chemical reactions can help analyze the activity of the specific enzyme catalase, which can be found in bovine liver and yeast. Our hypothesis regarding enzyme activity is that the aspects of biology and environmental factors contribute to the different enzyme activities between bovine liver and yeast.
Catalase is a common enzyme that is produced in all living organisms. All living organisms are made up of cells and within the cells, enzymes function to increase the rate of chemical reactions. Enzymes function to create the same reactions using a lower amount of energy. The reactions of catalase play an important role to life, for example, it breaks down hydrogen peroxide into oxygen and water. Our group developed an experiment to test the rate of reaction of catalase in whole carrots and pinto beans with various concentrations of hydrogen peroxide. Almost all enzymes are proteins and proteins are made up of amino acids. The areas within an enzyme speed up the chemical reactions which are known as the active sites, and are also where the
Abstract: Enzymes are catalysts therefore we can state that they work to start a reaction or speed it up. The chemical transformed due to the enzyme (catalase) is known as the substrate. In this lab the chemical used was hydrogen peroxide because it can be broken down by catalase. The substrate in this lab would be hydrogen peroxide and the enzymes used will be catalase which is found in both potatoes and liver. This substrate will fill the active sites on the enzyme and the reaction will vary based on the concentration of both and the different factors in the experiment. Students placed either liver or potatoes in test tubes with the substrate and observed them at different temperatures as well as with different concentrations of the substrate. Upon reviewing observations, it can be concluded that liver contains the greater amount of catalase as its rates of reaction were greater than that of the potato.
Background information:. Enzyme Enzymes are protein molecules that act as the biological catalysts. A Catalyst is a molecule which can speed up chemical reactions but remains unchanged at the end of the reaction. Enzymes catalyze most of the metabolic reactions that take place within a living organism. They speed up the metabolic reactions by lowering the amount of energy.
In this experiment as a whole, there were three individual experiments conducted, each with an individualized hypothesis. For the effect of temperature on enzyme activity, catalase activity will be decreased when catalase is exposed to temperatures greater than or less approximately 23 degrees Celsius. For the effect of enzyme concentration on enzyme activity, a concentration of greater or less than approximately 50% enzymes, the less active catalase will be. Lastly, the more the pH buffer deviates from a basic pH of 7, the less active catalase will be.
In the most general terms, the nucleus is the command center of a eukaryotic cell. Although the origin of the organelle is unclear, it is believed that it is derived from a symbiosis relationship between a bacterium and an archaea (Martin W. 2005). Being the main hub for the inner workings of a cell involves different functions overall. These nucleic functions are determined by the genes within the DNA of the cell. Functions of the cell are also regulate by soluble proteins that come in and out of the cell via the membranes and specific channels or the nuclear pore complexes. The overall objectives of the nucleus include; gene expression, compartmentalization, and processing pre-mRNA. The functions of the organelles and sub-regions
Cold Potato: that when the potato is cooled to 2-5 degrees the production of oxygen will be slowed as the catalase in the potato will become less active due to the molecules getting less kinetic temperature from the heat.
The purpose of this assessment was to research, design and conduct an experimental investigation on the effect of substrate concentration (manipulated by increasing concentration of pH buffer) of catalysed reactions by measuring the volume of oxygen produced as the reaction proceeded.
The Cathars were a very peaceful group that adopted a life of extreme devotion. Both men and women could become "parfaits". "Parfaits" referred to people who were seen by the Catholic Church as "perfect heretics". They renounced the world and abstained from eating meat and having any sexual contact. The Cathars lived in poverty. The men would travel and preach, and they earned money by cloth making, and shepherding. Followers were not expected to abide by the same ascetic standards as the parfaits, and they were permitted to eat meat and engage in sex. Catharism, or Albigensianism, was a religion which originated in the Balkans long before it made its appearance in the southwestern region of France , around the 12th century. It was a religion like any other, based on good versus evil. Albigensianism was a heretic religion and the catholics were not very fond of this new and upcoming religion. Its creed stated that god never created Earth, Jesus never existed nor did he suffer on the cross. The only ceremony practiced by the Cathars was the consolamentum or baptism of the Holy Spirit. For the Cathars, this was the only means of salvation. The Cathar clergy were those who had already received the consolamentum as part of the ritualistic ordination and had already been saved. The lay Cathars, or Believers, were obliged to receive the same sacrament before death in order to be saved as well. By the early thirteenth century Catharism was a very quickly growing religion in the area of Languedoc. It was supported by the nobility as well as the common people. This was yet another annoyance to the Roman Church. Even in open debates, Ca...
Enzymes have the ability to act on a small group of chemically similar substances. Enzymes are very specific, in the sense that each enzyme is limited to interact with only one set of reactants; the reactants are referred to as substrates. Substrates of an enzyme are the chemicals altered by enzyme-catalysed reactions. The extreme specific nature of enzymes are because of the complicated three-dimensional shape, which is due to the particular way the amino acid chain of proteins folds.
I woke up grumpy in my little cat cell as you could call it. I hate this place and I wish, I was home with my mom and my little brother. Oh how much I miss them. I heard a loud dinging comming from behined me, I was confused because it was my first day at the shelter and I didn't know what we what was going on.
for dark, mysterious, and bizarre works of fiction. His works sometimes reflected his life experiences and hardships he tried to overcome. Examples of the troubles in his life include alcoholism, having his works rejected over and over, being broke, and losing his family, even his beloved wife to tuberculosis. There is no wonder why his works are so dark and evil, they were taken from his life. A theme is defined as the major or central idea of a work. Poe’s short story, “The Black Cat”, contains six major themes that are discussed in this paper. They include the home, violence, drugs and alcohol, freedom and confinement, justice and judgement, and transformation.
It changes from blue to red with acids but loses its colour in the presence of certain chemicals, one of which is vitamin C. DCPIP solution can be used to test for the presence of vitamin C in foods. Hypothesis Orange juice has the highest content of vitamin C. Citrus fruits have a higher content of vitamin C. The orange and lemon juice contain more vitamin C than the pineapple juice. Furthermore, as lemons are more acidic than oranges, I predict that the orange juice will contain more vitamin C than the lemon juice. Vitamin C affects, the ph the more vitamin C the higher the ph. Variables Independent Variables Different fruit juices (Pineapple, orange and lemon).
Enzymes are protein molecules that are made by organisms to catalyze reactions. Typically, enzymes speeds up the rate of the reaction within cells. Enzymes are primarily important to living organisms because it helps with metabolism and the digestive system. For example, enzymes can break larger molecules into smaller molecules to help the body absorb the smaller pieces faster. In addition, some enzyme molecules bind molecules together. However, the initial purpose of the enzyme is to speed up reactions for a certain reason because they are “highly selective catalysts” (Castro J. 2014). In other words, an enzyme is a catalyst, which is a substance that increases the rate of a reaction without undergoing changes. Moreover, enzymes work with
Concepts In the first chapter, the therapeutic factors that stood out to me the most was instillation of hope. There is research that says most therapies operate through hope and conviction. Group therapists do all that they can to increase the patient’s belief and confidence in group therapy that works effectively. Also, it is important that therapists believe in themselves. The most important is that members learn from others who have similar problems how therapy can work for them in their life.
