Chapter 19, Problem 19.41QP

Interpretation Introduction

Interpretation:

The catalytic groups present at the active site of an enzyme has to be defined.

Concept Introduction:

The key steps of an enzyme-catalyzed reaction can be summarized as follows:

  $\begin{array}{l}\text{E}+\text{S }\stackrel{\text{fast}}{\rightleftarrows }\text{ ES }\stackrel{\text{slow}}{\rightleftarrows }\text{ E}+\text{P}\\ \left[\text{Enzyme-substrate}\right]\end{array}$

The first step of enzyme-catalyzed reaction begins with the formation of a complex between the enzyme and substrate that is referred to as enzyme-substrate complex. This complex is formed by the interaction between the functional groups present at the active site of the enzyme and the substrate molecule.
