Explanation / Answer

ATP acts as a source of energy to carry out reactions. It can either 1) couple with high activation-energy reactions and make them feasible, or 2) it can provide Phosphate to intermediates of any metabolic pathway.

NAD+ is reduced form as it has given it H ion. NADH is oxidized form.

NADH has more potential energy as it can undergo reduction and liberate energy.

NAD+ holds lesser potential energy.
