Q. If RQ is less than 1.0 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 the respiratory substrate consumed less oxygen than the amount of C$O_{2}$ released
Explanation
Ratio of the volume of carbon dioxide liberated to the volume of oxygen absorbed during respiration is called Respiratory Quotient (RQ) Carbohydrate – One Fat, protein - Less than one Organic acid - More than one Succulents - Zero
