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.

Margarita [4]

Answer:

Memories aren't just stored in one part of our brains. Different parts are stored in different brain regions, but the hippocampus is memories are formed and later accessed.

Explicit memories are conscious and can be verbally explained, however, implicit memories are usually nonconscious and are not verbally articulated.

Explanation: I'm sorry but I don't know the answer to your last question, so I hope you figure out the answer to that one...........also hope this at least helps you out somewhat:)
