Proton Gradient & ATP Synthesis — NEET Biology
📚 Practice ConceptWhy are we so interested in the proton gradient? This gradient is important because it is the breakdown of this gradient that leads to the synthesis of ATP. The gradient is broken down due to the movement of protons across the membrane to the stroma through the transmembrane
Assertion (A): ATP synthesis is directly dependent on proton gradient formation. Reason (R): Protons diffuse from lumen to stroma through ATP synthase, driving ATP production.
View solution & NCERT explanation
Correct answer: A — Both A and R true, R explains A
ATP synthesis is directly powered by proton flow through ATP synthase from high to low concentration.
