classify the following examples of enzymatic regulation as competitive inhibition or allosteric inhibition.
A.ethanol out competes methanol for binding to the enzyme alcohol dehydrogenase
B.adenosine triphosphate (ATP) prevents the synthesis of additional ATP by binding to a protein domain that does not include the active site
C.Isoleucine inhibits an enzyme binding to a regulatory domain that is separate from its catalytic domain
D.Ibuprofen binds tightly to the active side of cox enzymes instead of the natural substrate
