Which of the following is correctly related to aerobic respiration?

Options

  1. AOxygen acts as the first electron acceptor.
  2. BCytochrome c located towards inner side (matrix) of inner mitochondrial membrane.
  3. COxidation of 1 molecule of NADH gives rise to 2 molecules of ATP.
  4. DThe role of oxygen is limited to the terminal stage of the process.

Correct answer

D. The role of oxygen is limited to the terminal stage of the process.

Step-by-step solution

1 NADH is equivalent to 3 ATP. Oxygen is the terminal electron or proton acceptor in ETC. Cytochrome c is located towards IMS i.e. on the outer side of inner membrane of the mitochondria.
