Question

Part a - types of enzyme inhibitors complete this vocabulary exercise relating to the three types of enzyme inhibitors. drag the words on the left to the appropriate blanks in the sentences on the right. each word is used only once. view available hint(s) resethelp competitive active site substrate enzyme irreversible noncompetitive 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 .

Answer 1

1. A competitive inhibitor exhibits a composition, which is identical to the substrate that can combine with the enzyme just like the substrate.

2. A noncompetitive inhibitor combines with the enzyme that is not the active site.

3. Generally, a irreversible inhibitor produces a covalent bond with an amino acid group within the active site that inhibits the substrate from entering the active site or inhibits catalytic activity.

4. The competitive inhibitor competes with the substrate for the active site present on the enzyme.

5. When the noncompetitive inhibitor gets combined with an enzyme, the shape of the enzyme gets distorted.

6. The enzyme inhibitors disrupts the usual associations between an enzyme and its substrate.

Answer 2

1. Like the concept of a jigsaw puzzle, the competitive inhibitor has a similar structure with the substrate that they can match each other.
2. The noncompetitive inhibitor attaches itself away from the active site of the enzyme.
3. The irreversible/permanent inhibitor forms a covalent bond with an amino acid side group within the active site to prevent the substrate from entering the active site or prevent catalytic activity.
4. Active Site is the site where the competitive inhibitor attaches itself to the enzyme.
5. It is true that the noncompetitive inhibitor binds to the enzyme and causes the distortion of the shape.
6. The interaction between an enzyme and its substrate is disrupted by enzyme inhibitors.
