Verified Answer :

The correct answer is (B) because humans cannot produce alcohol when they are exercising. If so, then everyone would be drunk all the time!

In all seriousness, though, (A) ATP is a source of energy created when a phosphate group breaks off; therefore (A) and (D) are incorrect. (C) is a source of energy because lactic acid is the result of lack of oxygen in muscle cells. Therefore (C) is incorrect.

I hope this helps!

Alcoholic fermentation is not a source of energy for humans during exercise.

ENERGY:

  • Energy is a strict requirement for every metabolic or cellular activity. Energy is used by cells in form of ATP.

  • Human activities like walking, jumping, etc. cannot be done without energy input.

  • This energy (ATP) is synthesized in cells via a process called cellular respiration. However, in absence of oxygen, cells can undergo a kind of anaerobic respiration called lactic acid fermentation.

  • Therefore, alcoholic fermentation is not a source of energy for humans during exercise.
