Interpretation Introduction

(c)

Interpretation:

The terms reversible enzyme inhibitors and irreversible enzyme inhibitors are to be distinguished in the scientific terms.

Concept introduction:

Enzymes are the biochemical catalysts present in the human body or livings organism to catalyst their biochemical process. Enzymes fasten up the rate of reaction by a very large factor.

Inhibitors are the compounds that stops the working of the enzyme as a catalyst. Inhibitors are of two reversible enzyme inhibitors and irreversible enzyme inhibitors.

Expert Solution

Answer to Problem 59E

The enzyme includes an active site where the molecule of the substrate arrives and binds to the catalysis with the enzyme. The active site has the supplementary components displaying attraction forces to bind the molecule of the substrate to it. In the induced fit model, the bonding of the substrate with an enzyme was assumed to be reversible. That is, after the job is finished, it will leave the active site. Reversible enzyme inhibitors are molecules comparable to substrate molecules with the same type of atom or groups on the outside complementing the forces of attraction to occur at the active site. In this manner, the inhibitor blocks the active site accessible for the substrate and inhibits the biochemical reaction. Sometimes it has been discovered that the substrate stays attached to the active site which is its connection is irreversible. The compounds performing this type of activity are known as irreversible enzyme inhibitors.

Explanation of Solution

The Enzyme contains an active site where the substrate molecule comes and binds with the enzyme for the catalysis. The active site has complementary elements showing attraction forces in order to binds the substrate molecule to it. In the induced fit model, it was assumed that the bonding of substrate with an enzyme is reversible. That is it will leave the active site after the work is done. Reversible enzyme inhibitors are the molecules similar to substrate molecule having the same kind of atom or groups present on the outside that is complementary to the attraction forces to occur at the active site. In this way, inhibitor blocks the active site available for the substrate and inhibits the biochemical reaction. Sometimes it has been found that substrate remains bonded to an active site that is its bonding is irreversible. The compounds performing this kind of activity are known as irreversible enzyme inhibitors.

Conclusion

The terms reversible enzyme inhibitors and irreversible enzyme inhibitors are distinguished in the scientific terms rightfully above.

The enzyme includes an active site where the molecule of the substrate arrives and binds to the catalysis with the enzyme. The active site has the supplementary components displaying attraction forces to bind the molecule of the substrate to it. In the induced fit model, the bonding of the substrate with an enzyme was assumed to be reversible. That is, after the job is finished, it will leave the active site. Reversible enzyme inhibitors are molecules comparable to substrate molecules with the same type of atom or groups on the outside complementing the forces of attraction to occur at the active site. In this manner, the inhibitor blocks the active site accessible for the substrate and inhibits the biochemical reaction. Sometimes it has been discovered that the substrate stays attached to the active site which is its connection is irreversible. The compounds performing this type of activity are known as irreversible enzyme inhibitors.

Explanation of Solution

The Enzyme contains an active site where the substrate molecule comes and binds with the enzyme for the catalysis. The active site has complementary elements showing attraction forces in order to binds the substrate molecule to it. In the induced fit model, it was assumed that the bonding of substrate with an enzyme is reversible. That is it will leave the active site after the work is done. Reversible enzyme inhibitors are the molecules similar to substrate molecule having the same kind of atom or groups present on the outside that is complementary to the attraction forces to occur at the active site.

The enzyme includes an active site where the molecule of the substrate arrives and binds to the catalysis with the enzyme. The active site has the supplementary components displaying attraction forces to bind the molecule of the substrate to it. In the induced fit model, the bonding of the substrate with an enzyme was assumed to be reversible. That is, after the job is finished, it will leave the active site. Reversible enzyme inhibitors are molecules comparable to substrate molecules with the same type of atom or groups on the outside complementing the forces of attraction to occur at the active site. In this manner, the inhibitor blocks the active site accessible for the substrate and inhibits the biochemical reaction. Sometimes it has been discovered that the substrate stays attached to the active site which is its connection is irreversible. The compounds performing this type of activity are known as irreversible enzyme inhibitors.

Explanation of Solution

The Enzyme contains an active site where the substrate molecule comes and binds with the enzyme for the catalysis. The active site has complementary elements showing attraction forces in order to binds the substrate molecule to it. In the induced fit model, it was assumed that the bonding of substrate with an enzyme is reversible. That is it will leave the active site after the work is done. Reversible enzyme inhibitors are the molecules similar to substrate molecule having the same kind of atom or groups present on the outside that is complementary to the attraction forces to occur at the active site. In this way, inhibitor blocks the active site available for the substrate and inhibits the biochemical reaction. Sometimes it has been found that substrate remains bonded to an active site that is its bonding is irreversible. The compounds performing this kind of activity are known as irreversible enzyme inhibitors.
