Question

In what way is ATP production in chloroplasts similar to that in mitochondria?
Options
A Both use carbon dioxide as an electron acceptor
B Both use a proton gradient across a membrane to power ATP synthase
Correct Answer
C Both occur in the cytoplasm
D Both convert water into oxygen for energy
Correct Answer

Option B is the correct answer.

Detailed Explanation

Both organelles generate ATP through chemiosmosis. They create a proton gradient across a membrane (thylakoid in chloroplasts, inner mitochondrial membrane) and use the enzyme ATP synthase to harness the energy of proton flow.

Hint

The core mechanism of oxidative phosphorylation and photophosphorylation is the same.
