(a)

Interpretation Introduction

Interpretation:

The nature of inhibition shown by phenylthiourea has to be determined.

Concept Introduction:

Certain inhibitors may compete to bind at the active site of the enzyme as they resemble the structure of the natural substrate of that particular enzyme. They may occupy the active site for a transient period of time as they are held by only weak forces and thus dissociate quickly. They are termed as reversible competitive inhibitors. Unlike the case of irreversible inhibition they are bound strongly via covalent interaction that does not allow the inhibitor to dissociate from the active site. The significance of such inhibition is that it can be reversed if the natural substrate can be bound to the enzyme with stronger forces or if the concentration of the natural substrate is increased.
