NAD (Nicotinamide adenine dinucleotide). The cellular respiration processes of all living cells make use of the coenzyme Nicotinamide adenine dinucleotide (NAD). It plays a key role in energy metabolism by accepting and donating electrons.The low energy form NAD + shown at left is raised to the high energy form NADH.icotinamide adenine dinucleotide phosphate or NADPH is a reduced coenzyme that plays a key role in the synthesis of carbohydrates in photosynthetic organisms. It is the reduced form of NADP + and as such is a high energy molecule that helps drive the Calvin cycle.
The electron acceptor in photosynthesis is NAD+ while in respiration the electron acceptor is NADH. In cellular respiration reaction 36 molecules of ATP are produced in complete oxidation of one molecule of glucose.
