Chapter 21, Problem 21.42AP

Interpretation Introduction

Interpretation:

The intermediate formed due to catabolism of carbohydrate, lipids and proteins should be identified.

Concept Introduction:

Digestion: It is one of the body processes in which food gets converted into smaller particles which get suitable for absorption of proteins, lipids and carbohydrates.

Metabolism: The process by which living organisms synthesize energy they required is known as metabolism. Mainly there are two pathways

1. 1. Catabolism
2. 2. Anabolism

The series of reaction present in these reactions is called as metabolic pathway.

First the consumption of food gets digested which results in production of small molecules.

Glycolysis is a pathway which describes conversion of one molecule of glucose into 2

Pyruvate molecules. It involves totally 10 set of reactions with it.

Krebs cycle essentially involves the oxidation of acetyl CoA to ${\text{CO}}_{\text{2}}\text{and}{\text{H}}_{\text{2}}\text{O}$. It is the final common oxidative pathway for carbohydrates, fats, amino acids.

The process of catabolism of fatty acids includes three major parts and they are,

Activation of fatty acid and its transport into mitochondria

Beta-oxidation

Electron transport chain
