Question

What does cellular respiration require

Answer 1

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

Answer 2

Cellular respiration is the cellular process which transfers chemical energy from glucose to ATP.

Step-by-step explanation:

Oxygen is essential to have efficient cellular respiration; most organisms need oxygen for a single purpose: to release energy from food for use by cells.
