A.

Summary Introduction

To explain: The effect of Feedback inhibition from Z to the step B àC

Introduction:

Mechanisms of inhibition by which cells’ metabolic pathways are controlled are called as feedback inhibition. Feedback inhibition is very essential in regulating the metabolism, as they limit the formation of the end product. In this, the end products of the reaction inhibit the enzyme that catalyzes the previous steps by binding to the allosteric site of that enzyme and inactivate them. As the earlier steps of the reaction do not occurred, the next of the reaction will not proceed.

B.

Summary Introduction

To explain: The effect of feedback inhibition from Z to the step Yà Z

Introduction:

Mechanisms of inhibition by which cells’ metabolic pathways are controlled are called as feedback inhibition. Feedback inhibition is very essential in regulating the metabolism, as they limit the formation of the end product. In this, the end products of the reaction inhibit the enzyme that catalyzes the previous steps by binding to the allosteric site of that enzyme and inactivate them. As the earlier steps of the reaction do not occurred, the next of the reaction will not proceed.

C.

Summary Introduction

To explain: Z as a positive regulator to regulate the step BàX

Introduction:

Mechanisms of inhibition by which cells’ metabolic pathways are controlled are called as feedback inhibition. Feedback inhibition is very essential in regulating the metabolism, as they limit the formation of the end product. In this, the end products of the reaction inhibit the enzyme that catalyzes the previous steps by binding to the allosteric site of that enzyme and inactivate them. As the earlier steps of the reaction do not occurred, the next of the reaction will not proceed.
