Oxidation reduction reactions ________.

Question

Quizplus · Accepted Answer

Oxidation reduction reactions involve the transfer of electrons from one molecule to another. Oxidation is the loss of electrons and reduction is the gain of electrons. In many cases, this involves the loss of hydrogen atoms, which carry electrons, from molecules that are being oxidized and the addition of hydrogen atoms to molecules that are being reduced. Therefore, option B is correct. Option A is incorrect because hydrogenases are enzymes that catalyze the transfer of electrons to or from hydrogen gas (H2) and are not directly involved in oxidation reduction reactions. Option C is incorrect because oxidation reduction reactions are often coupled together to provide energy for biological processes. Option D is incorrect because oxidation involves the loss of electrons or the gain of oxygen, while reduction involves the gain of electrons or the loss of oxygen.
