NEET Previous Year Question
Which of the following combinations is required for chemiosmosis?
Topic: NEET PYQ
Answer: B. Full step-by-step solution below.
- AProton pump, electron gradient, NADP synthase
- BMembrane, proton pump, proton gradient. ATP synthase
- CMembrane, proton pump, proton gradient, NADP synthase
- DProton pump, electron gradient, ATP synthase
Correct answer: B
Solution
(b) Chemiosmosis requires a membrane, a proton pump, a proton gradient and ATP synthase.Energy is used to pump protons across a membrane, to create a gradient or a high concentration of protons within the thylakoid lumen. ATP synthase has a channel that allows diffusion of protons back across the membrane; this releases enough energy to activate ATP synthase enzyme that catalyses the formation of ATP.
