In a pathway that is regulated by feedback inhibition, all of the following are true except:

a.
the product of the pathway might bind to an earlier enzyme in the pathway at an allosteric site

b.
the product of the pathway could alter the shape of an earlier enzyme in the pathway such that the enzyme can no longer bind substrate

c.
the product of the pathway might bind to an earlier enzyme in the pathway and lock it into an active conformation

d.
the product of the pathway is most likely to interact with the first enzyme in the pathway
