During a reaction, a coenzyme like NAD⁺ functions by

A. Providing the primary structural scaffold for the apoenzyme
B. Acting as a temporary acceptor of specific atoms or functional groups
✓
C. Shifting the reaction's equilibrium constant
D. Binding irreversibly to the product

📝 Explanation

A coenzyme acts as a co-substrate; it binds, accepts a chemical group from one substrate, and transfers it to another, being regenerated in the process.
