The process of ATP synthesis through a combination of chemical and osmotic events is known as:
Correct answer: C. Oxidative phosphorylation
- A. Fermentation
- B. Glycolysis
- C. Oxidative phosphorylation
- D. Oxidation of pyruvate to acetyl CoA
Explanation
Oxidative phosphorylation is the final stage of cellular respiration, where most of the cell's ATP is produced. This process occurs in the inner mitochondrial membrane and relies on an electron transport chain (ETC) and chemiosmosis.

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.
