Show Answer

Answer:

Correct Answer: 53.( a )

Solution:

  1. (a) In the given diagram of aerobic respiration
  • pathway A is glycolysis, pathway B is Kreb’s cycle and pathway $C$ is ETS , thus $4,8 & 12$ are ATP. ATP act as energy currency. The energy is trapped in form of ATP and it is broken down whenever and wherever it needs to be utilised.
