Question

During cellular respiration, cells obtain energy for performing work when...

I. energy-rich molecules of glucose are broken down in the cytoplasm, and ATP is produced.
II. enzyme pathways in the mitochondria produce ATP through the process of fermentation.
III. enzyme pathways in the mitochondria produce ATP in a process that requires oxygen.

Answer 1

III. enzyme pathways in the mitochondria produce ATP in a process that requires oxygen.

Answer 2

The correct answer is option III. enzyme pathways in the mitochondria produces ATP in a process that requires oxygen.

Step-by-step explanation:

Hello!

Let's solve this!

During cellular respiration, oxygen is captured and then released carbon dioxide.

The oxygen obtained is used to obtain ATP by enzymatic routes.

We conclude that the correct answer is option III. enzyme pathways in the mitochondria produces ATP in a process that requires oxygen.
