Answer:

b) In allosteric regulation, a small molecule binds to a large protein and causes it to change its shape and activity.

Explanation:

Allosteric regulation refers to the activity control of an enzyme by binding small molecules to regulatory sites on It. This binding causes an alteration of the protein conformation and consequently the shape of the active site and its catalytic activity are altered. Regulatory enzymes can act by either stimulating or inhibiting the activity of a protein.
