Question 42 (1 point) How do competitive and noncompetitive enzyme inhibitors differ? Competitive inhibitors bind to the active site, whereas noncompetitive inhibitors change the shape of the active site. Competitive inhibitors have a higher energy of activation than noncompetitive inhibitors have. Noncompetitive enzyme inhibitors are reversible, whereas competitive inhibitors are irreversible. Noncompetitive enzyme inhibitors contain magnesium, whereas competitive inhibitors contain iron. They function at different pH values. Question 43 (1 point) How might an enzyme inhibitor slow down the action of an enzyme without binding to the active site? by binding the substrate by binding to another site on the enzyme and changing its shape by lowering the activation energy by changing the shape of the substrate

irreversible 1. A (n) inhibitor has a structure that is so similar to the substrate that it can bond to the enzyme just like the substrate. 2. A (n) inhibitor binds to a site on the enzyme that is not the active site. 3. Usually, a(n) inhibitor forms a covalent bond with an amino acid side group within the active site, which prevents the substrate from entering the active site or prevents catalytic activity. 4. The competitive inhibitor competes with the substrate for the on the enzyme. 5. When the noncompetitive inhibitor is bonded to the enzyme, the shape of the is distorted. 6. Enzyme inhibitors disrupt normal interactions between an enzyme and its . enzyme substrate competitive active site noncompetitive

Which of the followings is NOT true? An uncompetitive inhibitor binds only to the enzyme-substrate complex. The binding site of an uncompetitive inhibitor is created after the substrate binds to the enzyme An alkaline phosphatase is an enzyme that catalyzes the addition of a phosphate group to a protein or other molecules A competitive inhibitor often resembles the substrate and binds to the active site of the enzyme to form enzyme-inhibitor complex, thereby preventing the binding of the substrate to the active site A noncompetitive inhibitor has a different binding site from that of the substrate. A noncompetitive inhibitor can bind to the enzyme or enzyme-substrate complex
