List the ways in which a metabolic block can have phenotypic effects.

Summary Introduction

To explain: The ways in which a metabolic block can have phenotypic effects.

Introduction: Metabolic blocks are said to occur when a metabolic process is hindered due to some reason. It is mainly caused due to some enzyme defect. These enzymatic defects can be due to improper functioning or due to deficiency of the enzymes that are involved in the metabolic pathway. Metabolic blocks can display wide range of phenotypic effects on the organism.

Explanation of Solution

Metabolic blocks hinder the biochemical pathways that are used to break down biochemical entities into simpler forms. These mainly affect the chemical reactions that are taking place during the process of digestion. Necessary chemical entities obtained from the food materials are not broken down due to metabolic blocks which cause problems to the person suffering from these metabolic blocks. Sometimes these metabolic blocks can also become fatal due to their physiological effects. Incomplete or abnormal metabolic pathways taking place due to metabolic blocks produce certain unwanted materials that can cause harmful effects. Some of the physiological effects of certain metabolic blocks are as follows:

  • Deficiency of glucose-6-phosphate causes glycogen storage disease that can cause liver enlargement...
