Respiration In Plants Question 1

Question: Which of the following combination is required for chemiosmosis?

(1) proton pump, electron gradient, NADP synthase

(2) membrane, proton pump, proton gradient, ATP synthase

(3) membrane, proton pump, proton gradient, NADP synthase

(4) proton pump, electron gradient, ATP synthase

Show Answer

Answer: (2) membrane, proton pump, proton gradient, ATP synthase

Explaination-

Chemiosmosis requires a membrane, a proton pump, a proton gradient, and ATP synthase. The proton gradient is broken down due to movement of proton across the membrane to the lumen through the transmembrane channel of the ATPase
