Energy capture efficiency of the aerobic cells using glucose as a substrate is

1. 50%
2. 40%
3. 30%
4. 20%

Correct Option: C

Complete aerobic metabolism of glucose produces water and carbon dioxide as products.
C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O
Energy is released in this process. The overall “G of glucose breakdown is -720 kcal/mole. Normally about 32% of the energy is released is captured through the formation of ATP the remainder is released as heat.
