Question

The amount of energy given by one ATP molecule is

• A. 67 Kcal.
• B. 6.7 Kcal.
• C. 7.6 Kcal.
• D. 76 Kcal.

Answer 1

The correct option is C 7.6 Kcal.

In all living cells, energy is temporarily packaged within a remarkable chemical compound called adenosine triphosphate (ATP), which holds readily available energy for very short periods.

ATP hydrolysis produces about 28 and 37 kJ/mol, or 6.8 to 8.7 kcal /mol.

So, the correct answer is option C.
