Every cell in the body requires oxygen for respiration so that sufficient energy can be produced. carbon dioxide, a waste product, is also produced and needs tone removed. therefore, the levels of both gasses must be regulated. how does this explain the changes in your pulse rate?
me google isn’t doing its job and i’m so confused

as explained below:

Explanation:

it results as follow:

while you are jogging or doing any physical activity than your body requires alot of energy and produce a lot of carbon dioxide which causes the heart to beat fast as to remove co2 and take o2 from the blood leading to higher rate of pulse.

on the secon hand if you are sedentary , consumption and production of o2 and co2 respectively will decrease leading to the slow beating of heart leading to low pulse

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.
