Answer 2

Answer:

Explained below

Explanation:

(1) Anaerobic respiration (oxygen is absent): Here the first step is the break-down of glucose which is six carbon into a three carbon molecule called pyruvate in the cytoplasm. Further, the pyruvate may be converted into ethanol and carbon dioxide in yeast.

(2) Aerobic respiration (oxygen is present) : During aerobic respiration, first six carbon glucose is broken down into pyruvate and then the three carbon pyruvate molecule is broken down to give three molecules of carbon dioxide and water in mitochondria.
