Question

during the complete oxidation of glucose by aerobic respiration, a maximum of 4 atp molecules are made by substrate-level phosphorylation, compared to how many atp molecules made by oxidative phosphorylation?

Answer 1

The number of ATP molecules made by oxidative phosphorylation is 28 ATP.

Oxidative phosphorylation is the next step in aerobic energy metabolism after glycolysis and the Krebs cycle. This stage itself is a combination of the electron transport chain followed by a chemiosmosis process whose result is ATP.

• 1 NADH produces 2.5 ATP

• 1 FADH₂ generates 1.5 ATP.

The process of aerobic respiration produces 10 NADH and 2 FADH2.

• The amount of ATP produced from 10 NADH is 10 x 2.5 = 25 ATP
• 2 FADH2 produces 2 x 1.5 = 3 ATP.

So, the total ATP generated is 28 ATP.
