Medical Author: William C. Shiel Jr., MD, FACP, FACR; Phosphorylation: A biochemical process that involves the addition of phosphate to an organic compound. And what they do is they take the high energy electrons that are being carried by NADH or ~ and they pass them one to the next which is why collectively it's called an electron transport system. Glucose is first phosphorylated to glucose-6-phosphate with an enzyme called hexokinase. Level. Gravity.

Both NADH and NADPH consist of two ribose molecules, which are attached together by phosphate groups and one ribose is connected to an adenine group, and the other ribose is connected to a nicotinamide group. Definition of nadh word . Biology. NADH dehydrogenase subunit 2 (ND2) proteins contribute to electron transfer and hydrogen to produce ATP through the progress of Phosphorylation. The process starts by catalyzing the oxidation of NADH to NAD + by transferring the two electrons to FMN, thus reducing it to FMNH 2.
