THE EFFECT OF EXERCISE ON CELLULAR RESPIRATION

Introduction:

Cellular respiration is the process that cells use to break down glucose; this releases energy that is used to produce ATP.  Cellular respiration involves a series of enzyme-catalysed reactions.

The equation below shows the complete oxidation of glucose during aerobic cellular respiration. Oxygen is required for this energy-releasing process to occur.

C6H12O6 + 6O2 € 6CO2 + 6H2O + 686 kilocalories of energy/mole of glucose oxidized

By studying the equation above, you will notice there are three ways cellular respiration could be measured. One could measure the:

  1. Consumption of O2
  2. Production of CO2
  3. Release of energy during cellular respirationl

In this experiment the relative rate of CO2 production will be measured. Bromthymol blue (BTB) is an indicator that turns yellow in the presence of an acid. Since CO2 combines with H2O to produce carbonic acid, BTB can be used to detect the presence of CO2.

Since exercising requires more energy than resting, the effect of the cellular
