What is the total gain of energy during this process?
Options
- AOne molecule of ATP
- BTwo molecules of ATP
- CFour molecules of ATP
- DEight molecules of ATP
Correct answer
B. Two molecules of ATP
Step-by-step solution
Anaerobic respiration is an enzyme-controlled, partial break down of organic compounds (food) without using oxygen and releasing only a fraction of the energy. It is also called intra-molecular respiration. The respiration results in incomplete degradation of the substrate to CO2 and organic compounds like ethyl alcohol, lactic acid etc. accompanied by the release of some energy. A number of ATP molecules evolved in one complete cycle of anaerobic respiration is 2.
