ATP Synthase Structure & Function — NEET Biology
📚 Practice ConceptThe ATP synthase enzyme consists of two parts: one called the CF₀ is embedded in the thylakoid membrane and forms a transmembrane channel that carries out facilitated diffusion of protons across the membrane. The other portion is called CF₁ and protrudes on the outer surface of the thylakoid membrane on the side that faces the stroma. The break down of the gradient provides enough energy to cause a conformational change in the CF₁ particle of the ATP synthase, which makes the enzyme synthesise several molecules of energy-packed ATP.
Assertion (A): ATP synthase produces multiple ATP molecules during photosynthesis. Reason (R): The breakdown of the proton gradient causes conformational change in CF1 particle of ATP synthase, enabling the enzyme to synthesize energy-packed ATP.
