The effect of pH on anaerobic respiration in S. cerevisiae
Introduction:
In the process of cellular respiration ATP (adenosine triphosphate) molecules are formed from a catalyzed decomposition of sugar molecules. This process consists of a long series of biochemical reactions which are necessary for providing cells with essential chemical energies stored in the form of ATP to be utilized later on. There are two types of respiration: the aerobic respiration and the anaerobic respiration and their occurrence depend on the availability of oxygen. If an organism is exposed to sufficient amount oxygen it will perform the aerobic respiration while the anaerobic respiration happens when the organism’s environment lacks oxygen. Even though both types of respiration result in the production of ATP molecules, the aerobic respiration is considered to be more efficient than the anaerobic. Aerobic respiration can achieve production of significantly higher levels of ATP per molecule (such of 34 ATP per sugar molecule) of sugar when compared to anaerobic respiration (2 ATP per sugar molecule) (Respiration, Cellular, 2015).

Although all organisms, including S. cerevisiae, actively maintains homeostasis, the organism’s environmental acidity or basicity will prevent its ability to maintain such balance. Changes in the acidity of the environment can directly impact the intercellular pH in S. cerevisiae, thus influencing the activities of enzymes. Therefore, the influence of pH condition on enzymes can be observed in the rates of respiration, enzyme activity largely influences the respiratory proccess . As the optimal condition for S. cerevisiae growth is pH 5.4 and the temperature of 30°C ((Shafagat et al., 2010), it was predicted that the rates of respiration would also be greatest at this pH and

    gars. These are then split into two three-carbon sugar phosphates and then these are split into two pyruvate molecules. This results in four molecules of ATP being released. Therefore this process of respiration in cells makes more energy available for the cell to use by providing an initial two molecules of ATP.

    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.

    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.

    Humans, and all animals, use adenosine triphosphate (ATP) as the main energy source in cells. The authors of Biological Science 5th edition said that “In general, a cell contains only enough ATP [adenosine triphosphate] to last from 30 seconds to a few minutes”. It is that way “Because it has such high potential energy, ATP is unstable and is not stored”. They also state that “In an average second, a typical cell in your body uses an average of 10 million ATP molecules and synthesizes [makes] just as many”. In the human body trillions of cells exist. The average human body uses and makes 10,000,000,000,000,000 molecules of ATP every second. In one minute the human body uses 600,000,000,000,000,000 molecules of ATP. In one day the human body uses 864,000,000,000,000,000,000 molecules of ATP. In one year, this is equivalent to 365.25 days; the average human body uses and makes a huge amount, 315,576,000,000,000,000,000,000 molecules of ATP. For this example one mile is equal to one molecule of ATP. Light travels at approximately 186,000 mi/sec. It would take light roughly 53,763,440,860 years to travel that many miles. The sheer amount of ATP made in the cells of people is amazing! This essay will explain somewhat the main way of making all of those ATP molecules in aerobic organisms, aerobic cellular respiration. There are four steps that take place in aerobic cellular respiration, and they are: 1.Glycolysis; 2. Pyruvate Processing; 3. Citric Acid Cycle; 4. Electron Transport and Oxidative Phosphorylation (Allison, L. A. , Black, M. , Podgoroski, G. , Quillin, K. , Monroe, J. , Taylor E. 2014).

    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. In my hypothesis for comparison #4 the measurements would go up again with every 15 min. intervals because of the high tempeture and also be higher that then Controlled Table’s measurements. Hypothesis was right for the first part but was wrong for the second part of the comparison, the measurements did increase in the table’s personal flask but the measurements did not get higher than the Controlled Table’s measurements, see chart below. In conclusion, I feel that the substitution of glucose for sucrose made the enzymes work just as hard as the Controlled Table’s flask but just not as much because sucrose was too strong for the enzymes to

    This lab attempted to find the rate at which Carbon dioxide is produced when five different test solutions: glycine, sucrose, galactose, water, and glucose were separately mixed with a yeast solution to produce fermentation, a process cells undergo. Fermentation is a major way by which a living cell can obtain energy. By measuring the carbon dioxide released by the test solutions, it could be determined which food source allows a living cell to obtain energy. The focus of the research was to determine which test solution would release the Carbon Dioxide by-product the quickest, by the addition of the yeast solution. The best results came from galactose, which produced .170 ml/minute of carbon dioxide. Followed by glucose, this produced .014 ml/minute; finally, sucrose which produced .012ml/minute of Carbon Dioxide. The test solutions water and glycine did not release Carbon Dioxide because they were not a food source for yeast. The results suggest that sugars are very good energy sources for a cell where amino acid, Glycine, is not.
