INTRODUCTION TO CELLULAR RESPIRATION IN YEAST
Cellular respiration is the process where glucose is released as energy in the form of ATP. Cellular respiration occurs in two ways. During anaerobic respiration, energy is produced without oxygen. The fermentation of yeast can occur because the yeast cells have the capability to undergo cellular respiration without the presence of oxygen. Yeast is able to break down sugar into glucose, causing the release of carbon dioxide. During the process of glycolysis, the initial two ATP molecules are what activate the glucose. Two NADH molecules are produced, causing two additional ATP molecules to be produced. Temperature is a factor that affects the rate of cellular respiration in yeast. It alters the amount of energy used as well as the amount of oxygen needed. Since yeast is a living organism, temperature is needed to activate its energy production. When too high a temperature is present, the yeast organisms die which causes the absence of carbon dioxide and energy.
To determine the differences in the rate of cellular respiration of yeast at varying temperatures.
