Q6. Why can't an enzyme have a kcatK... [FREE SOLUTION]

Chapter 12: Q6. (page 373)

Why can't an enzyme have a $\frac{k_{cat}}{K_{M}}$ value greater than $10^{9} M^{鈥� 1} s^{鈥� 1}$ ?

Short Answer

Expert verified

The $\frac{k_{cat}}{K_{M}}$ value cannot be greater than $10^{9} M^{鈥� 1} s^{鈥� 1}$ because this value is near the diffusion-controlled limit.

Step by step solution

Introduction

Enzymes are biological catalysts that catalyze chemical reactions. These are proteins that minimize the activation energy required to initiate chemical reactions.

Enzyme has a greater value

This rate cannot be faster than the diffusion-controlled encounter of an enzyme and its substrate. No enzyme can have a diffusion limit greater than $10^{9} M^{鈥� 1} s^{鈥� 1}$ , and this enzyme is working with maximum efficiency.

Thus, no enzyme can have $\frac{k_{cat}}{K_{M}}$ greater than the value $10^{9} M^{鈥� 1} s^{鈥� 1}$ .
