Why is oxygen central to the existence of animal life? Use reactions to explain.

Interpretation Introduction

Interpretation:

Using equations, the reason that oxygen is important to the existence of animal life is to be explained.

Concept Introduction:

The process that involves the production of energy due to the intake of oxygen and release of carbon dioxide from the environment by cells within tissues is called respiration.

The capacity of an object to do work is called energy.

Explanation of Solution

About 21% of Earth’s atmosphere contains oxygen, and around 25% of the oxygen inhaled reaches the blood stream with each breath. This oxygen is transported to the cells. The oxygen molecules, on reacting with glucose, provide energy. This process is called respiration. This can be explained by the following reaction:
