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.
Nicotinamide Adenine Dinucleotide (NAD) is a dinucleotide that functions as one of the most important coenzymes in the cell. The interconversion of NAD between the reduced (NADH) and oxidized (NAD+) forms is a common reaction in biological redox (oxidation-reduction) reactions.In cells, most oxidations are accomplished by the removal of hydrogen atoms. Each molecule of NAD + can acquire two electrons; that is, be reduced by two electrons.he oxidizing agent is NAD+, which is reduced to NADH. The process is exergonic and the mechanism that has evolved allows the energy of reaction to be captured as two moles of ATP per glucose molecule: 2 NAD +. 2.
