Electron transport chain explains:
Correct answer: D. Mechanism of ATP synthesis
- A. Photophosphorylation
- B. Z-Scheme
- C. Photolysis
- D. Mechanism of ATP synthesis
Explanation
The electron transport chain is a key component in the mechanism of ATP synthesis. During oxidative phosphorylation, which is the final stage of cellular respiration, the electron transport chain creates a proton gradient across the inner mitochondrial membrane. This gradient drives the synthesis of ATP through the action of ATP synthase.

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.
