    the answer is B but I could not really see the connection between structure types and active site of the enzyme. @ari

    The key here is to remember that the enzyme has a quaternary structure because we deal with 2 polypeptides. They mention the amino acid sites just to confuse you, the answer would be the same even if they wouldn’t mention the active site or the position of the amino acids.

    2 chains= 2 different subunits made= Primary, secondary, tertiary, quaternary.They said each chain has something to do with the active site, so both chains are associated with it and thus all structures of protein exist. If they said only 1 amino chain is associated then u would most probably choose primary secondary and tertiary.

    2 chains=> 2 subunits=> all protein structures are included. They said both chains are associated with the active site=> quaternary exists.
