SummaryCells need energy to do work to carry out metabolic processes that keep them alive and functioning. This energy is stored in the form of ATP, which stands for adenosine triphosphate. All plant and animal cells use a process known as cellular respiration to make ATP from carbohydrates. Plant cells also have a process known as photosynthesis that they use to fixate carbon into carbohydrates using energy from the sun. However, even in plant cells, the most important energy contribution is made by cellular respiration, since ATP formed during photosynthesis is used primarily to fixate the carbon atoms for later use in glycolysis (a step of cellular respiration). Cellular respiration can either be carried out aerobically (in the presence of oxygen) or anaerobically (in the absence of oxygen) (Miyazaki, 85). This lab is concerned with testing the anaerobic pathway, namely alcohol fermentation.
Table of Contents
- Alcohol fermentation occurs after glycolysis, instead of the Krebs cycle.
- The first experiment involved setting up a standard protocol, so that we could become familiar with the apparatus that measures the water displacement by CO2 and simultaneously see the affect of yeast concentration on fermentation rate.
- Following the conclusion of the standard protocol, we set up another experiment using the same set up.
- With respect to the standard protocol experiment, there is one main reason why the data turned out as it did.
- In conclusion, according to our experiment, fermentation is greatly affected by yeast concentration and pH levels.
