The CO2 concentration in expired air at the "breaking point" of a breath hold is, therefore, a very consistent index of the maximum duration of the breath hold. In other words, the duration of a breath hold is determined mainly by how long it takes to reach the body's upper CO2 set-point for …

The respiratory quotient is the ratio of CO2 production to O2 consumption. We measure CO2 production by measuring the CO2 in the exhaled gas; since the inhaled gas essentially has no CO2 in it, everything exhaled is considered to be produced by the body.

6 CO2 + 6 H2O + 36 ATP (energy) This lab will address how exercise (increased muscle activity) affects the rate of cellular respiration. You will measure heart rate as an indicator of the need for oxygen. You will measure these indicators at rest (with no exercise) and after 1, 2 and 3 minutes of exercise. Materials(stop watch. PreLab

A by-product of aerobic respiration is carbon dioxide (CO2). Thus, the release of CO2 in our exhaled breath should be an indicator of the amount of oxygen (O2) consumed. We will assay the amount of CO2 in exhaled air by exploiting the fact that CO2, when mixed with water, forms carbonic acid, in the manner shown by the following chemical reaction:

It can be measured directly through invasive monitoring, or indirectly by measuring the CO2 content in your exhaled air. You can also infer hypocapnia by the presence of some of the symptoms, illnesses, and conditions that can be triggered or worsened by CO2 deficit due to over-breathing: Feelings of breathlessness, shortness of breath
