Define Respiratory Quotient (RQ) and calculate the respiratory quotien

1.	Define Respiratory Quotient (RQ) and calculate the respiratory quotient of carbohydrate.
Answer» Ratio of volume of `CO_(2)` evolved to the volume of `O_(2)` consumed in respiration is known as Respiratory Quotient (RQ). When carbhoydrates are used as respiratory substrate and are completely oxidized , the RQ is 1 , because volume of `CO_(2)` evolved is equal to the volume of `O_(2)` consumed . RQ for carbohydrate is : `RQ = (6CO_(2))/( 6 O_(2)) = 1*0` `C_(6)H_(12)O_(6)+6 O_(2) to 6 CO_(2) + 6 H_(2)O` + energy.
