Every cell in the body requires oxygen for respiration so that sufficient energy can be produced. Carbon dioxide, a waste produc

Answer:

as detailed below:

Explanation:

The outcomes are as follows:

During exercise or any physical activity, the body demands significant energy, resulting in increased carbon dioxide production. This escalation causes the heart to pump faster to expel CO2 while absorbing O2 from the bloodstream, thus elevating the pulse rate.

In contrast, when one is inactive, both oxygen consumption and carbon dioxide production decline, leading to a slower heartbeat and consequently a reduced pulse rate.
