If an individual is eating a diet in which 25% of their ATP production is a result of utilizing carbohydrates, 50% of their ATP production is a result of metabolizing fats, 25% of their ATP production is a result of metabolizing proteins, their cardiac output is 4.7 L/min, and their arterial-venous oxygen difference is 6.2 mL/dL, how much carbon dioxide are they producing

Oxidative phosphorylation proceeds with the formation of energy laden molecules i. e; carbondioxide and water.

Therefore, Total CO₂ production is directly related to VCO₂ = R x VO₂

where, R is the respiratory quotient varing among 0.7 to 1.0 according to the energy intake (ATP) ie 0.25 of the total diet consumed.

VO₂ is, as mentioned above arterial venous oxygen difference = 6.2ml/dl

therefore, VCO₂ = 0.25 x 6.2

= 1.55 ml/dl

ie; VO₂ : VCO₂ = 6.2 : 1.55.
