Oxidation reduction reactions ________.

Question

Quizplus · Accepted Answer

Oxidation reduction reactions involve the transfer of electrons, which may be accompanied by the transfer of protons (H+ ions). The molecule undergoing oxidation loses electrons and may also lose protons, while the molecule undergoing reduction gains electrons and may also gain protons. Therefore, oxidation reduction reactions may involve the loss of hydrogen and electrons. Option A is partially correct but not comprehensive enough as oxidation reduction reactions also involve the loss of electrons and gain of oxygen. Hydrogenases are not always involved in these reactions, so option B is incorrect. Option C is incorrect as oxidation and reduction reactions are often coupled together in biological systems.
