When you add yeast to dough, it rises because:
(a) yeast cells reproduce by budding
(b) yeast cells from colonies
(c) of the bulk of new yeast cells
(d) the rapidly reproducing yeast cells release due to anerobic respiration

Correct Answer: (d) the rapidly reproducing yeast cells release due to anaerobic respiration

Explanation:

 The anaerobic process takes place in yeast during fermentation.

It takes place in the absence of oxygen.
 Ethanol, carbon dioxide, and energy are the final products during anaerobic respiration in plants (like yeast).
