Why is the Respiratory Exchange Ratio (RER)
greater than 1 at maximum work intensities?
Oxygen consumption is higher than
CO<sub>2</sub> production
Lactic acid suppresses mitochondrial
metabolism
Excess CO2 is exhaled relative to O2
consumption

Expert Solution

Step 1

The ratio between the carbon dioxide volume produced and the oxygen volume used in the metabolism is known as the respiratory exchange ratio (RER). The value of RER can indicate the type of fuel source i.e. fats, carbohydrates, or proteins.
