How does nadh differ from nadph

NADH is produced in glycolysis and Krebs cycle and is used in the electron transport chain to produce ATP via oxidative phosphorylation. NADPH is produced in the light reaction of photosynthesis and is used in the Calvin cycle to assimilate carbon dioxide. NAD is one of the most abundant types of coenzyme inside the cell, involving in the oxidation-reduction reactions of the cellular respiration.

It is mainly used in catabolic reactions. NADH is produced in glycolysis and Krebs cycle. FADH 2 is also produced in Krebs cycle. Nicotinamide adenine dinucleotide, or NAD, is in all living cells , where it functions as a coenzyme.

Note that "donate a proton" and "accept a pair of electrons" translates to the same thing in biochemistry. NADH contains two phosphate groups linked by an oxygen molecule. Each phosphate group joins a five-carbon ribose sugar. One of these in turn links to an adenine molecule, while the other links to a nicotinamide molecule.

NADH takes part in metabolism by accepting and donating electrons, with the energy driving this flowing from the cellular citric acid cycle or tricarboxylic acid TCA cycle. This electron transport occurs in cellular mitochrondrial membranes. NADPH also contains two phosphate groups linked by an oxygen molecule.

As in NADH, each phosphate group joins a five-carbon ribose sugar. Unlike the case with NADH, however, the same five-carbon ribose sugar that joins adenine carries a second phosphate group, for a total of three phosphate groups in total. What is NADH 4. It has a Vitamin B backbone. Therefore, it is a water-soluble compound. As it is positively charged, it can act as an oxidizing agent. It oxidizes other compounds and converts to its reduced form which is NADH. Also, synthesis also takes place through modification of niacin which is taken from the diet.

It is also a coenzyme. It works as a reducing agent and oxidizes itself while reducing the other compound. Hence, NADH is useful in many catabolic reactions as an electron carrier. Furthermore, NADH acts as a coenzyme in the citric acid cycle.
