   ---   Definition of cellular respiration: Respiration is a serial flow of  electrons from an oxidizable substrate (like sugars) to an ultimate  electron acceptor (like oxygen) resulting in the generation of  energy, which is used in various cellular needs.
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.
