Question
Which one of the following is not true regarding the release of energy during ATP synthesis through chemiosmosis? It involves:
Breakdown of proton gradient
Breakdown of electron gradient
Movement of protons across the membrane to the stroma
Reduction of NADP to on the stroma side of the membrane
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. The NADP reductase enzyme is located on the stroma side of the membrane. Along with the electrons that come from the acceptor of electrons of PS I, protons are necessary for reduction of NADP to . The process does not involve breaking of electron gradient.
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from General. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
