Question

A 2010 paper reports an average resting rate of axygen consumption (Vo2 in sitting individuals to be 3.7 ml/min/kg, implying that the "average 70 kg man" is consuming appraximately 15.5 liters of pure O2 every hour while seated. If an individual were consuming 15.5 L of pure O2 and was utilizing almost entirely glucose metabolism, they would be producingL of pure CO2 per hour, whereas if they were utilizing almost entirely fatty acid metabolism, they would be producing_L of pure CO2 per hour. 15.5; 15.5 15.5; 12.4 O 15.5; 11 O 11; 15.5 0 12.4; 15.5

Explanation / Answer

Answer: 3rd option

Explanation :

Respiratory Quotient (R.Q) for Glucose =1

R.Q = V(CO2) / V(O2)

=>1= V(CO2) / 15.5

=> V(CO2) =15.5 Liter

Respiratory Quotient (R.Q) for Fatty acid =0.71 (approx.)

R.Q = V(CO2) / V(O2)

=>0.71= V(CO2) / 15.5

=> V(CO2) =15.5 x 0.71 Liter

=> V(CO2) = 11 liter
