In this lab, we will observe the effect of food source on the process of cellular respiration by yeast. You will attempt to determine whether a yeast “bread dough” contains only flour or flour and sugar, based on the rate of CO2 production. You will assess CO2 production by measuring how much the dough rises in a set period of time. MATERIALS:
