The electron transport chain of mammalian mitochondria contains 3 multienzyme protein complexes that convert the energy of oxidationreduction reactions into a form that can be used for the synthesis of ATP and for the uptake of solutes. This form of energy is most likely an example of which of the following?

Question

Quizplus · Accepted Answer

The energy from the electron transport chain is primarily used to create a proton gradient across the inner mitochondrial membrane, which is then used to drive ATP synthesis through chemiosmosis.  The normal flow of electrons, through the proteins of the oxidative phosphorylation machinery, is coupled with the establishment of a proton gradient across the inner mitochondrial membrane. The establishment of this pH gradient is the chemiosmotic potential that is coupled with the production of ATP.
