Hypotheses: • Aerobic: If succinate is added to certain test tubes, then the percent transmittance of the mixtures in those tubes will increase. This is caused by the resulting higher oxidation states making DCPIP bluer, no due to the amount of mitochondrial suspension. • Anaerobic/Fermentation (A): If the temperature is greater than or less than room temperature (21.11ºC/294.26 K), then the difference in final volume from initial volume will be positive and larger than room temperature. However, after a certain temperature, the values of the difference between final volume and initial volume will start to decrease. • Anaerobic/Fermentation (B): If the alternative sugars are heated at a constant temperature of 45ºC (318.15 K), then some of …show more content…

This process can be performed in two stages: aerobic (presence of oxygen during process) and anaerobic (no presence of oxygen during process). During aerobic cellular respiration, the process uses the products from the glycolysis cycle, Krebs (citric acid) cycle, and electron transport chain. During anaerobic cellular respiration, the process only uses the products from the glycolysis cycle and fermentation, which is split into either lactic acid process (in muscle cells and produces lactate as byproduct) or alcohol process (happens with yeast products, and causes NADH to donate electrons to pyruvate and convert it into …show more content…

During the second experiment, it was observed that test tube 2 at room temperature did not have a change in volume. In similar fashion, test tube 5 did not have significant change in the volume, only adjusting by +0.4 mL. In the ice (0˚C), test tube 1 had a change of 1.3 mL, while in warmer temperatures above room temp. and below 100˚C had changes upward of 3.5mL+. The reasoning behind this is that since these processes are enzymatic, the enzymes work productively in a certain temperature range. When reaching extreme or baseline temperatures, the enzymes slow down their process (i.e. tubes 2 and 5). The hypothesis is supported, however, it does not give a more detailed interest as to what temp. range works best. In the experiment, it was determined that the ideal temperature was

    After conducting this experiment and collecting the data I would have to say that the optimal temperature for enzyme activity would have to be room temperature which in my experiment was thirty-four degrees Celsius. I came to this answer because the glucose test strip showed that at room temperature there was more glucose concentration that at either of the other temperatures. Due to temperature extremes in the boiling water the enzymes could no longer function because the breakdown of lactose stopped. The cold water also hindered the breakdown of the lactose but as the water warmed the enzymes were more active which can be seen in the results for the cold water at 20 minutes B. Describe the relationship between pH and the enzymatic activity of lactase.

  • Rate of Respiration in Yeast

    Rate of Respiration in Yeast Aim: I am going to investigate the rate of respiration of yeast cells in the presence of two different sugar solutions: glucose, sucrose. I will examine the two solutions seeing which one makes the yeast respire faster. I will be able to tell which sugar solution is faster at making the yeast respire by counting the number of bubbles passed through 20cm of water after the yeast and glucose solutions have been mixed. Prediction: I predict that the glucose solution will provide the yeast with a better medium by which it will produce a faster rate of respiration. This is because glucose is the simplest type of carbohydrate (monosaccharide).

    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.

  • Cellular Respiration Essay

    596 Words  | 2 Pages

    Do you know how you are able to run long distances or lift heavy things? One of the reasons is cellular respiration. Cellular respiration is how your body breaks down the food you’ve eaten into adenosine triphosphate also known as ATP. ATP is the bodies energy its in every cell in the human body. We don’t always need cellular respiration so it is sometimes anaerobic. For example, when we are sleeping or just watching television. When you are doing activities that are intense like lifting weights or running, your cellular respiration becomes aerobic which means you are also using more ATP. Cellular respiration is important in modern science because if we did not know about it, we wouldn’t know how we are able to make ATP when we are doing simple task like that are aerobic or anaerobic.

  • Citric Acid Cycle And The Krebs Cycle

    1511 Words  | 4 Pages

    That is when muscles switch from aerobic respiration to lactic acid fermentation. Lactic acid fermentation is the process by which muscle cells deal with pyruvate during anaerobic respiration. Lactic acid fermentation is similar to glycolysis minus a specific step called the citric acid cycle. In lactic acid fermentation, the pyruvic acid from glycolysis is reduced to lactic acid by NADH, which is oxidized to NAD+. Lactic acid fermentation allows glycolysis to continue by ensuring that NADH is returned to its oxidized state (NAD+). When glycolysis is complete, two pyruvate molecules are left. Normally, those pyruvates would be changed and would enter the mitochondrion. Once in the mitochondrion, aerobic respiration would break them down further, releasing more

    In our Biology Lab we did a laboratory experiment on fermentation, alcohol fermentation to be exact. Alcohol fermentation is a type of fermentation that produces the alcohol ethanol and CO2. In the experiment, we estimated the rate of alcohol fermentation by measuring the rate of CO2 production. Both glycolysis and fermentation consist of a series of chemical reactions, each of which is catalyzed by a specific enzyme. Two of the tables substituted some of the solution glucose for two different types of solutions.

    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

    ...remain the same at 4ºC and 25ºC. The final result of this experiment was that glucose was more present in environments of higher temperatures. Our hypothesis and predictions were wrong because lower temperatures do not break down the enzymes because they become denatured. The enzyme activity decreases once the temperature decreases, as well. Enzyme activity increases when there is a rise in temperature, which is why lactose is broken down in much higher temperatures, resulting in a high presence of glucose.

    Yeasts are facultative anaerobes. They are able to metabolize the sugars in two different ways which is aerobic respiration in the presence of oxygen and anaerobic respiration in the absence of oxygen. The aerobic respiration also known as cellular respiration takes place when glucose is broken down in the present of oxygen to yield carbon dioxide, water and energy in the form of ATP. While in anaerobic respiration, fermentation takes place because it occurs in the absence of external electron acceptor. Because every oxidation has to be coupled to a reduction of compound derived from electron donor. On the other hand, in cellular respiration an exogenous

    When humans consume plants, the carbohydrates, lipids, and proteins are broken down through two forms of cellular respiration. The two processes of cellular respiration displayed in humans are anaerobic and aerobic. The deciding process used depends on the presence of oxygen. Cellular respiration converts the material into a useable energy called ATP. ATP is the energy form that cells can use to perform their various functions, and it can also be stored for later use.
