Chapter 25, Problem 25.43E

Interpretation Introduction

Interpretation:

The ultimate use for the ${\text{O}}_2$ in the cell is to be stated. Whether the ${\text{O}}_2$ that is inhaled, incorporated into the ${\text{CO}}_2$ that is exhaled is to be explained. The source of ${\text{CO}}_2$ that is exhaled is to be described.

Concept introduction:

A person needs oxygen to provide energy to the body for various cellular processes. This ultimately occurs when oxygen accepts electron during the electron transport chain or oxidative phosphorylation process. This process ultimately produces high energy adenosine triphosphate $\left(\text{ATP}\right)$ molecules that can be used to produce useful chemical energy to conduct desired reaction.
