Which of the following are reactants in the process of aerobic respiration?

A.

glucose and water

B.

carbon dioxide and water

C.

glucose and oxygen

D.

carbon dioxide and oxygen

The answer is B. Water and Carbon dioxide.

Aerobic respiration is a catabolic process in which a fuel molecule such as glucose is broken down to form carbon dioxide and water. It includes redox reactions that result in the transfer of electrons from glucose (which becomes oxidized) to oxygen (which becomes reduced).
