ligand Correct Answer-a small molecule that binds specifically to a larger one (i.e., protein). For example, a hormone is the ligand for its specific protein receptor [a molecule bound reversibly by a protein. 
 
binding site Correct Answer-the location (crevice or pocket) on a receptor protein to which a ligand binds 
 
induced fit Correct Answer-The change in shape of the active site of an enzyme so that it binds more snugly to the substrate, induced by entry of the substrate. Renders the subs...
