Which one of the following is not true regarding the release of energy during ATP synthesis through chemiosmosis? It involves:
- ABreakdown of proton gradient
- BBreakdown of electron gradient
- CMovement of protons across the membrane to the stroma
- DReduction of NADP to on the stroma side of the membrane
Solution & Step-by-step Explanation
Chemiosmosis requires a membrane, a proton pump, a proton gradient, and ATP synthase.Energy is released when the proton gradient is broken down as protons move through the channel.Incorrect statement: There is no "electron gradient" involved in the direct synthesis of ATP; electrons are part of the transport chain that creates the proton gradient.Protons move from the lumen to the stroma.NADP reduction occurs on the stroma side, contributing to the gradient.
