Individuals without AFS have a glutamic acid at position 487 on the ALDH2 protein, whereas individuals with AFS have a lysine at
azamat

Answer:

Aldehyde Dehydrogenase 2 (ALDH2) is an enzyme required to eliminate toxins such as acetaldehyde and alcohol, thereby mutations in this protein may be associated with the Alcohol flush syndrome (AFS)

Explanation:

ALDH2 is a protein required for ATP generation by catalyzing the oxidation of aldehydes to carboxylic acids (i.e., oxidation of NADH to NAD+). Mutations in the ALDH2 gene have been associated with the inactive form of this enzyme, and this specific mutation at position 487 alters its enzymatic activity associated with the metabolism of acetaldehyde and alcohol. This amino acid substitution may lead to the active site-directed inactivation of the enzyme.

2. In the citric acid cycle, malate is oxidized to oxaloacetate by the enzyme malate dehydrogenase, which uses NAD+ as an electr
atroni [7]

Answer:

NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.

Explanation:

NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.

             NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.

         Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.

              That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get  low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.
