Detailed explanation-1: -Enzyme inhibitors are compounds which modify the catalytic properties of the enzyme and, therefore, slow down the reaction rate, or in some cases, even stop the catalysis. Such inhibitors work by blocking or distorting the active site.

Detailed explanation-2: -Listen to pronunciation. (EN-zime in-HIH-bih-ter) A substance that blocks the action of an enzyme. Enzymes help speed up chemical reactions in the body and take part in many cell functions, including cell signaling, growth, and division.

Detailed explanation-3: -Inhibitors are chemical or biological molecules that regulate chemical reactions by slowing down or blocking them from occurring. Inhibitors often work to slow or stop enzymes-proteins that catalyze reactions.

Detailed explanation-4: -An irreversible inhibitor inactivates an enzyme by bonding covalently to a particular group at the active site. A reversible inhibitor inactivates an enzyme through noncovalent, reversible interactions. A competitive inhibitor competes with the substrate for binding at the active site of the enzyme.

Detailed explanation-5: -The competitive inhibitor binds to the active site and prevents the substrate from binding there. The noncompetitive inhibitor binds to a different site on the enzyme; it doesn’t block substrate binding, but it causes other changes in the enzyme so that it can no longer catalyze the reaction efficiently.
