Introduction ATP is a source of energy required by cells to undergo and perform daily functions. These molecules are produced through the catabolism of carbohydrates, fats and proteins. Sources of ATP can be generated under aerobic respiration and anaerobic respiration, in the presence of oxygen and presence of no oxygen, respectively. Fermentation occurs as well, without oxygen. Fermentation and anaerobic respiration are not the same type of metabolism; they both use a different terminal electron …showed first 75 words of 1360 total…

…showed last 75 words of 1360 total…we take measurements, especially reading the scale, it is not always accurate. As we take more measurements, then larger discrepancy in the data results. To research in depth of increasing doses of ethanol on the production of CO2 is to perform other tests, such as using other species of yeast cells or other eukaryotic cells to test glucose metabolism. Measuring only Saccharomyces cerevisiae is not enough to suggest that inhibitors like ethanol decrease cell metabolism.
