Question

Electron carriers such as nicotinamide adenine dinucleotide (NAD) are used in energy capturing processes such as photosynthesis and respiration. They play a central role in the redox reactions that occur at the time of energy harvest from the carbon source.
What is the function of an oxidizing agent?

• A. Molecules that donate electrons.
• B. A molecule that becomes oxidized.
• C. A molecule that gains electrons.
• D. Molecules that combines with oxygen.
