The complexes within electron transport chains A) are "circuits" for small amounts of electricity to pass through B) contain NADH that transports electrons C) transport H⁺ into the mitochondrial matrix D) are in the mitochondrion's inner membrane E) all of these

Question

Quizplus · Accepted Answer

Electron transport chains are located in the inner membrane of the mitochondrion. Choice A is incorrect because while electrons do pass through the complexes, the process is not analogous to the passage of small amounts of electricity through a circuit. Choice B is partially correct in that NADH is involved in transporting electrons, but it is not contained within the complexes themselves. Choice C is not a function of the complexes within electron transport chains.
