Verified Answer :

Answer:

1. option D, 360

2. Option A, oxygen is present

3. Option C, three molecules of carbon dioxide.

4. Electron transport chain

Explanation:

1. In break down of one molecule of glucose, 36 molecules of ATP are released thus break down of ten molecules of glucose will release 360 molecules of ATP.

2. In case if oxygen is present in the kerb cycle , then the pyruvic acid oxidizes itself and loses a carbon dioxide and forms acetyl coenzyme A (CoA)

3. The pyruvic acid (containing three molecule of carbon) formed with in a kerb cycle releases its three carbon in the form of three molecules of carbon dioxide

4. The structure in the image is mitochondria and the process is ETC where energy molecules are formed at the end of the process.
