Question

3 multiple choice 1 point which of the following is an energy carrier molecule that helps in redox reactions? nadh adp ribose co₂

Explanation:

NADH (nicotinamide - adenine dinucleotide, reduced form) is an energy - carrying molecule involved in redox reactions. It donates electrons in the electron transport chain. ADP (adenosine diphosphate) is related to energy transfer but not directly in redox reactions like NADH. Ribose is a sugar molecule and CO₂ is a product of many metabolic reactions, neither of which are energy - carrier molecules for redox reactions.

Answer:

A. NADH
