NADH is also used by cells when making certain molecules. Based on your knowledge of the role of NADH in cellular respiration, what do you think NADH's role is in biosynthesis of molecules?1. Oxidising molecules2. Phosphorylating molecules3. Dehydrating molecules4. Reducing molecules

2. Phosphorylating molecules

Explanation:

NADH and NADPH are coenzymes resulting from the reduction of NAD⁺ and NADP⁺ (through electron transfer).

Although NADH and NADPH are almost identical in structure, they have different functions.

NADH uses free energy from oxidation of metabolites to synthesize ATP (oxidative phosphorylation), while NADPH uses energy for reducing biosynthesis of fatty acids, cholesterol and other substances.

4. Reducing molecules

Explanation:

NADH is a cofactor and is short for nicotinamide adenine dinucleotide. That is critical in cellular respiration since it accepts and donates electrons to facilitate redox reactions. During many of these cell cycles the biosynthesis of molecules often involve NADH which is oxidised to NAD+. NADH is an electron donor as well. In these cases it acts as a reducing agent to other molecules.
