Q. If RQ is 0.6 in a respiratory metabolism, it would mean that
A) Carbohydrates are used as respiratory substrate
B) Organic acids are used as respiratory substrate
C) The oxidation of the respiratory substrate consumed more oxygen than the amount of C$O_{2}$ released
D) The oxidation of respiratory substrate consumed less oxygen than the amount of C$O_{2}$ released
Explanation
RQ is the ratio of volume of carbon dioxide evolved and volume of oxygen consumed. If RQ is less than one it means the oxidation of the respiratory substrate consumed more oxygen than the amount of carbon dioxide released. Volume of carbon dioxide < Volume of oxygen
