Question

Explain how NAD is regenerated.

Answer 1

NAD takes up H atoms in glycolysis to form NADH2. this NADH2 then enters the electron transport chain. in this complex 1 which is NADH dehydrogenase removes these H atoms to give NAD+. this NAD+ then goes back to glycolysis and this process continues.

Answer 3

the ques is about regenration...but if u want to know about generation then i can check in my books and tell u

Answer 4

Most organisms synthesize NAD+ from simple components.[2] The specific set of reactions differs among organisms, but a common feature is the generation of quinolinic acid (QA) from an amino acid—either tryptophan (Trp) in animals and some bacteria, or aspartic acid in some bacteria and plants.[21][22] The quinolinic acid is converted to nicotinic acid mononucleotide (NaMN) by transfer of a phosphoribose moiety. An adenylate moiety is then transferred to form nicotinic acid adenine dinucleotide (NaAD). Finally, the nicotinic acid moiety in NaAD is amidated to a nicotinamide (Nam) moiety, forming nicotinamide adenine dinucleotide.[2]

Answer 6

got it? @nincompoop

Answer 7

Thank you a lot :)

Answer 8

obviously NAD would be present in the new born's cell.basically the NAD generated in a new born's cell would be a self molecule. these new born's have tolerence ie not to react on self cells and its components so neither innate nor acquired immunity is triggered.

Answer 9

state where reduced nad molecules are re-oxidised and describe what happens to the hydrogen atoms.
