Chapter 21.3, Problem 21.5Q

Interpretation Introduction

Interpretation:

The substrate-level phosphorylation has to be explained.

Concept Introduction:

The proteins, carbohydrate, and fat are the energy source in the diet. Before they are used to produce cellular energy, they break down into smaller subunits such as simple sugars, glycerol, fatty acids, and amino acids. In order to break the macromolecules into simple units, several processes are used to change the substrate into its activated form. One of the examples of these processes is phosphorylation process that adds a phosphate group to the substrate molecule.
