Chemiosmosis involves
Correct answer: C. Proton gradient driving ATP synthesis
- A. Active transport of electrons
- B. Passive diffusion of protons
- C. Proton gradient driving ATP synthesis
- D. Direct phosphorylation of ADP
Explanation
Chemiosmosis uses the proton gradient across the inner mitochondrial membrane to drive ATP synthesis through ATP synthase.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
