Q. The respiratory quotient during cellular respiration would depend on :
(a) Amount of CO2 released
(b) Amount of O2 utilised
(c) The nature of enzymes involved
(d) Both (a) and (b)
Solution :
Correct option : D
Respiratory quotient is the ratio of the volume of carbon dioxide evolved to that of oxygen consumed by an organism, tissue, or cell in a given time. Therefore the respiratory quotient depends on both the amount of oxygen utilized and the amount of carbon dioxide generated.
