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.The change in the form of the active nicotinamide group in NADH is indicated above. It accepts two electrons and a hydrogen in reaching the high energy state. The NAD + is used in redox reactions in the cell and acts as a reducing agent.he change in the form of the active nicotinamide group in NADH is indicated above.
