Question
Which of the following is NOT a part of the Mitchell chemiosmotic hypothesis? A portion of the energy from electron transport is used in generation of a proton-motive force that in turn provides the energy for ATP synthesis. The use of electron transfer to provide the energy for ATP synthesis requires an intact membrane. High-energy phosphorylated intermediates that serve as phosphate donors to ADP are generated as a result of electron-transfer reactions. ATP production is driven by the formation of a gradient of protons between the matrix (low proton concentration) and the intermembrane space (high proton concentration).

High-energy phosphorylated intermediates that serve as phosphate donors to ADP are generated as a result of electron-transfer reactions.
Explanation:
Mitchell chemiosmotic hypothesis
-the proton gradient that causes a proton motive force that allows ATP synthase to phosphorylate ADP and inorganic phosphate to ATP.
-this theory doesn’t suggest coupling of high energy phosphate molecules to ATP synthesis.
