Which of the following is true concerning the electron transport chain? A) The associated oxidation and reduction reactions provide the energy needed to pump H⁺ ions into the mitochondrial matrix B) The flow of H⁺ ions from the inter-membrane space back into the mitochondrial matrix powers the (aerobic) production of ADP C) The electrons passed down the chain will eventually be used to help form water D) The end result of the electron transport chain is the formation of oxygen

Question

Quizplus · Accepted Answer

The electron transport chain passes electrons through a series of oxidation-reduction reactions that ultimately results in the formation of water. Therefore, option C is true. Option A is incorrect because H^and are not involved in the electron transport chain. Option B is also incorrect because the flow of ions from the inter-membrane space back into the mitochondrial matrix does not directly power the production of ADP. Option D is incorrect because oxygen is not formed, but rather it acts as the final electron acceptor in the chain to ultimately form water.
