Explanation:
Detailed explanation-1: -Carbohydrates come equipped with one oxygen for every carbon, and only need one additional oxygen per carbon to metabolize aerobically. Fats do not contain oxygen (in the fuel-part of the molecule), and need two additional oxygens per carbon to metabolize aerobically.
Detailed explanation-2: -Fat, on the other hand, creates a larger energy yield, but requires 2.4x more oxygen to metabolise than a CHO. The percentage of fat and CHO metabolism is determined by dividing carbon dioxide production by oxygen consumption and is called the Respiratory Exchange Ratio (RER).
