Biological oxidation-reduction reactions never involve: A)transfer of e^- from one molecule to another. B)formation of free e^-. C)transfer of H⁺ (or H₃O⁺)from one molecule to another. D)formation of free H⁺ (or H₃O⁺). E)none of the above.

Question

Quizplus · Accepted Answer

Biological oxidation-reduction reactions involve the transfer of electrons (e-) from one molecule to another. However, free electrons are never formed during these reactions. This eliminates choices A, C, and D. Additionally, choice E is incorrect because at least one of the options is not true. Therefore, the best answer is B, which states that biological oxidation-reduction reactions never involve the formation of free electrons.
