Chapter 22, Problem 22RQ

(a)

Summary Introduction

To define: The terms glucose, glycogenolysis, glycogenesis, gluconeogenesis, glucagon, and glycolysis and the relation between them.

Introduction: Metabolism is defined as the sum of all chemical reactions taking place in the body. Metabolic pathway is of two types: anabolic pathway and catabolic pathway.

Anabolic pathway is associated with the synthesis of large molecules and catabolic pathway is associated with the breakdown of large molecules.

(b)

Summary Introduction

To determine: The terms shivering thermogenesis, non-shivering thermogenesis, and diet-induced thermogenesis and the relation between them.

Introduction: Homeostasis is the mechanism of the body by which it maintains a constant temperature throughout the body.

(c)

Summary Introduction

To determine: The terms lipoproteins, chylomicrons, cholesterol, HDL-C, LDL-C, and apoproteins and the relation between them.

Introduction: Proteins are the large, complex biomolecules that play several important roles in the body.

(d)

Summary Introduction

To determine: The terms direct and indirect calorimetry and the relation between them.

Introduction: Metabolic rate defines the rate of metabolism. It the amount of energy used by a living organism per unit of time.

(e)

Summary Introduction

To determine: The terms conductive heat loss, radiant heat loss, convective heat loss, and evaporative heat loss and the relation between them.

Introduction: Heat loss from the body takes place by radiation, conduction, convection, and evaporation.

(f)

Summary Introduction

To determine: The terms absorptive and postabsorptive states and the relation between them.

Introduction: Metabolism is defined as the all chemical reactions that takes place in the body. The metabolic pathway that synthesizes large molecules from smaller ones is known as an anabolic pathway. The pathway that breaks a large molecule into smaller one is called catabolic pathway.
