Solution

To determine which molecules are oxidizing agents, we need to understand the concept of oxidation and reduction. In a redox reaction, oxidation refers to the loss of electrons, while reduction refers to the gain of electrons.

Looking at the options provided:

A. FAD and FADH2: FAD (flavin adenine dinucleotide) and FADH2 (reduced form of FAD) are involved in redox reactions as electron carriers. FAD can accept two electrons and two protons to form FADH2, which means it can be reduced. Therefore, FAD and FADH2 can act as oxidizing agents.

B. FAD+ and NAD+: FAD+ (oxidized form of FAD) and NAD+ (oxidized form of nicotinamide adenine dinucleotide) are both in their oxidized states. Since they can accept electrons and be reduced, they cannot act as oxidizing agents.

C. FADH2 and NADH: FADH2 and NADH (reduced form of NAD+) are both in their reduced states. As they can donate electrons and be oxidized, they cannot act as oxidizing agents.

D. NAD+ and NADH: NAD+ is the oxidized form of NAD, while NADH is the reduced form. NAD+ can accept electrons and be reduced, so it cannot act as an oxidizing agent. On the other hand, NADH can donate electrons and be oxidized, making it an oxidizing agent.

Therefore, the correct answer is option D: NAD+ and NADH.
