Chapter 22, Problem 19RQ

(a)

Summary Introduction

To determine: The effect of insulin on glycolysis.

Introduction: Glycolysis is the basic pathway that is used for metabolism of glucose. During this process, glucose, which is a 6 carbon molecule, is converted into a 3 carbon molecule called pyruvate. ATP molecules are also formed during the process of Glycolysis.

(b)

Summary Introduction

To determine: The effect of insulin on gluconeogenesis.

Introduction: Production of sugar molecules in the body is called gluconeogenesis. This sugar is used for energy production and different catabolic reactions. Liver is the main site where the process of gluconeogenesis takes place.

(c)

Summary Introduction

To determine: The effect of insulin on glycogenesis.

Introduction: Glycogen is a metabolic pathway that is involved in converting glucose in to glycogen for storage purpose. Glycogen produced by this process is stored in the cells of liver and muscles. Process of glycogenesis is activated when blood sugar level goes high.

(d)

Summary Introduction

To determine: The effect of insulin on lipogenesis.

Introduction: Lipogenesis is the process of formation of lipids using the extra sugar that is present in the blood. This fat produced by the process of lipogenesis is stored in the body for further use. Lipogenesis contributes only a small share to the total body fat content.

(e)

Summary Introduction

To determine: The effect of insulin on protein synthesis.

Introduction: Protein synthesis is the process of formation of functional proteins. Presence of all the required materials in adequate amount is very important for synthesis of properly functioning protein molecules.

Blurred answer
Students have asked these similar questions
It is noticed that when a strain of mice exercises, their blood glucose drops to very low levels. Which of the following can explain this situation? a) These mice do not make enough insulin b) these mice lack insulin receptors on their cells c)these mice lack glucagon d) these mice cannot synthesize glycogen from glucose
Low insulin to glucagonratio is seen in all of these except :-  A) glycogen synthesis  B) glycogen breakdown  C) gluconeogenesis  D) ketogenesis
Insulin will tend to increase (More than one answer may be correct): A)  gluconeogenesis B)  glycogenolysis C)  glycogenesis D)  protein degradation E)  lypolysis
