Intro
All living things are made out of cells. Some things such as E.coli and Hay bacillus are single-celled organisms other known as unicellular organisms. Other things like worms, humans, fungi, and plants are multicellular organisms. Unicellular and multicellular organisms need a few things to live. These things are a way to dispose of waste, an environment that the organism can adapt to, and these organisms need food too. Most cells take in oxygen, this oxygen that is taken in actually help give your body energy. How? Well, when the cells in your organs take in oxygen it breaks down the sugar from your food, and this gives you energy. This process is called cellular respiration. Cellular respiration is very important for the following experiment. This experiment is to prove that unicellular organisms can breathe. To do this will have yeast suspension ( a single-celled organism) in a small little cup hooked to a big oval cup by a small tube. This

The objective of the experiment was to change the large oval cups liquid from the color dark navy blue to dark yellow. The hypothesis that was made is “if unicellular organisms can breathe, then cellular respiration can happen”. Data that has been collected during this experiment shows that unicellular organisms can breath and cellular respiration can happen in any living organism. There were no patterns of any sort during this experiment. Also, according to the data table that yeast needs food to be alive. Errors that occurred during the experiment was mixing materials. For example, the water dropper accidentally became a mixer for the yeast. The way this problem can be fixed is to have one dropper for each liquid and keep that dropper next to that liquid. This will eliminate the mixing of liquids of any sort. Overall the findings of this experiment show that unicellular organisms can breath and cellular respiration can
Cellular respiration is the process by which energy is harvested involving the oxidation of organic compounds to extract energy from chemical bonds (Raven & Johnson, 2014). There are two types of cellular respiration which include anaerobic respiration, which can be done without oxygen, and aerobic respiration, which requires oxygen. The purpose of this experiment is to determine whether Phaseolus lunatus, also known as dormant seeds or lima beans, respire. You will compare the results of the respiration rate of the dormant seeds, and the Pisum sativum, or garden peas. In this experiment, you will use two constants which will be the temperature of the water and the time each set of peas are soaked and recorded. Using these constants will help
2. A test tube was then filled with 35ml of yeast and placed in the
The results shown in table 1 clearly show that when the volume of yeast is increased in the milk solution, so does the rate of oxygen depletion and therefore the rate of eutrophication. It shows that when 2mL of yeast solution was added it took 32.86 minutes on average for the milk to be depleted of oxygen, while it took only 7.46 minutes on average for the 10mL of yeast to use up the oxygen present.
This lab was done to determine the relationship of gas production to respiration rate. The lab was done with dormant pea seeds and germinating pea seeds. It was done to test the effect of temperature on the rate of cellular respiration in ungerminated versus germinating seeds. We had to determine the change in gas volume in respirometers. This was done to determine how much oxygen was consumed during the experiment. The respirometers contained either germinating, or non-germinating pea seeds. I think that the germinating seeds will have a higher oxygen consumption rate in a room temperature water bath than the non-germinating seeds. My reason for this hypothesis is that a dormant seed would not have to go through respiration because it is not a plant yet. A germinating seed would consume more oxygen because it is growing, and therefore would need to consume oxygen by going through the process of cellular respiration.
Black Star, composed of MC’s Mos Def and Talib Kweli, are joined by fellow rapper Common in their 1998 song “Respiration” to expose the decaying urban and societal conditions in their respective cities of Brooklyn and Chicago. Each artist paints a brilliant picture of their surroundings and deals with various issues which plague their communities. Mos Def’s verse is particularly well-written; in it he highlights the growing economic inequality, daily struggles of the inner city poor, and the overriding nature of the his city.
The Effects of Concentration of Sugar on the Respiration Rate of Yeast Investigating the effect of concentration of sugar on the respiration rate of yeast We did an investigation to find how different concentrations of sugar effect the respiration rate of yeast and which type of concentration works best. Respiration is not breathing in and out; it is the breakdown of glucose to make energy using oxygen. Every living cell in every living organism uses respiration to make energy all the time. Plants respire (as well as photosynthesise) to release energy for growth, active uptake, etc…. They can also respire anaerobically (without oxygen) to produce ethanol and carbon dioxide as by-products.
The purpose of this investigation is to test the effects of multiple sugar substances on the respiration of yeast. Most people think of yeast when they think of what makes bread rise, cheese, alcoholic beverages, or other food products. Another type of yeast can also cause yeast infections, an infection of the skin. Yeasts (Saccharomyces) are tiny, microscopic organisms with a thin membrane and are usually oval or circular-shaped. They are a type of single-celled fungi of the class Ascomycetes, capable of processing sugar into alcohol and carbon dioxide (CO2 ) ; this process is known as fermentation. Fermentation and the products are the main focus points for this experiment being that cellular respiration of yeasts happens via the process of fermentation, which creates by-products of alcohol and CO2. The level of CO2 produced by the yeasts will show how effective each sugar substance is in providing cellular energy for the yeasts.
If the amount of either hydrogen peroxide or yeast is different in any of the sections in the experiment then the results
The respiratory system has six major areas that works together that allows the body to breathe, prevent choking, and not to allow harmful debris to enter the respiratory system are some of the functions that the respiratory system does. The respiratory system is divided into two regions, the upper and lower respiratory. The upper respiratory consists of the Nose (nasal) and Pharynx while the lower respiratory embodies the rest of the system which includes the Larynx, Trachea, Bronchioles and Lungs. The information provided will be done by three individuals the upper respiratory tract will be provided by Mr. David Brown, the lower respiratory tract will be given by Ms. Brianna Agee and the infectious diseases will be provided by Mr. Derrek Woods.
The results have shown that test tubes one, four, five, and seven did bleach. This is because the process of respiration had occurred in those tubes; therefore, the dissolved oxygen levels were low and bleaching was forced to occur. Test tube one bleached because it contained glucose and the whole homogenate which includes both the cytoplasm and mitochondria. Glucose was used in the cytoplasm to fuel glycolysis to eventually lead to respiration. Test tube four had glucose and the supernatant which fueled glycolysis and lead to respiration causing the tube to bleach. Test tube five had succinate and the pellet, which means it was lead straight into the kreb’s cycle eventually making the tube bleach. Test tube seven is unique on the reason it bleached because glucose and succinate were already present from the broken up cells; therefore, glycolysis was occurring before the
In this discussion post we are to describe the structures and functions of the respiratory system. We were asked to include major organs and how they work within the body and to notate symptoms of failure within the respiratory system.
There were five test solutions used in this experiment, water being the control, which were mixed with a yeast solution to cause fermentation. A 1ml pipetman was used to measure 1 ml of each of the test solutions and placed them in separated test tubes. The 1 ml pipetman was then used to take 1ml of the yeast solution, and placed 1ml of yeast into the five test tubes all containing 1 ml of the test solutions. A 1ml graduated pipette was placed separately in each of the test tubes and extracted 1ml of the solutions into it. Once the mixture was in the pipette, someone from the group placed a piece of parafilm securely on the open end of the pipette and upon completion removed the top part of the graduated pipette.
Their table had 15 mL glucose, 10 mL RO water, and 10 mL of yeast which they then placed in an incubator at 37 degrees Celsius. In conclusion, I feel that the absence of RO water in the flask made the enzymes work a little harder than when the RO water was in the mixture of the flask. Comparison #4 is between the Controlled Table and Table #5. The mixture for that table’s flask was 15 mL Sucrose, 10 mL of RO water and 10 mL of yeast, which the flask was then placed in an incubator at 37 degrees Celsius.
From my reading I learned that cellular respiration is a multi-step metabolic reaction type process that takes place in each living organism 's cell rather it be plant or animal. It’s my understanding that there are two types of cellular respiration, one called aerobic cellular respiration which required oxygen and anaerobic cellular respiration that does not require oxygen. In the anaerobic cellular respiration process, unlike the aerobic process oxygen is not required nor is it the last electron acceptor there by producing fewer ATP molecules and releasing byproducts of alcohol or lactic acid. The anaerobic cellular respiration process starts out exactly the same as anaerobic respiration, but stops part way through due to oxygen not being
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
