Question

How much of the energy released during aerobic respiration is approximately conserved in the form of ATP?

• A. $20$%
• B. $40$%
• C. $60$%
• D. $100$%

Answer 1

The correct option is B $40$%

Aerobic respiration is the form of respiration which uses oxygen. It can be summarised by this equation:

glucose + oxygen → carbon dioxide + water (+ energy)

Each glucose molecule on complete oxidation gives 38 ATP molecules.

Approximately 40% of the energy is released during aerobic respiration is conserved in the form of ATP

So, the correct answer is '$40$%'
