Expert Answer:

The yeast cells feed on the sugar in the dough called glucose. They use anaerobic respiration to get energy for themselves from the glucose. In this process the yeast makes alcohol and carbon dioxide. The alcohol the yeast makes is called ethanol. Glucose makes ethanol and carbon dioxide; this process is called fermentation. The carbon dioxide fills the cakes dough with bubbles and rises making it fluffy.
