Chapter 4, Problem 14Q

A.

Summary Introduction

To explain: The ES in the given equation.

Introduction:

Enzymes are the protein molecules produced in a cell meant for catalyzing a biological process. The enzymes act upon certain molecules called as substrates and convert them into products. For enzyme reaction, there is a general equation called Michaelis–Menten equation. The equation is as follows:

$\text{E}\text{+}\text{S}\leftrightarrow \text{ES}\leftrightarrow \text{E}\text{+}\text{P}$

B.

Summary Introduction

To explain: The reason for bidirectional arrows and unidirectional arrow in the first and second step, respectively, in the given equation.

$\text{E}\text{+}\text{S}\leftrightarrow \text{ES}\leftrightarrow \text{E}\text{+}\text{P}$

C.

Summary Introduction

To explain: The cause for the presence of E at both ends of the equation.

Introduction:

$\text{E}\text{+}\text{S}\leftrightarrow \text{ES}\leftrightarrow \text{E}\text{+}\text{P}$

D.

Summary Introduction

To explain: The reason for the inhibition of the enzyme (E) due to the presence of high concentrations of product (P).
