Oxidative phosphorylation, synthesis of ATP in the presence of oxygen occurs in:
Correct answer: D. All Aerobic Cells
- A. All Types of Cells
- B. All Anaerobic Cells
- C. All Primitive Cells
- D. All Aerobic Cells
Explanation
Oxidative phosphorylation, which involves the synthesis of ATP in the presence of oxygen, occurs in aerobic cells. Aerobic cells are those that use oxygen as a final electron acceptor in the electron transport chain, leading to the production of water. This process takes place in the mitochondria of eukaryotic cells and in the inner membrane of the cell's mitochondria.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
