The apparatus used to measure the rate of respiration and the respiratory quotient $(RQ)$ is:

The diabetic patient shows:

The respiratory quotient $(RQ)$ of carbohydrates undergoing complete oxidation is $.......$.

Arrange the $RQ$ value of the following respiratory substrates in ascending order:
$(a) C_{4}H_{6}O_{5}$ (Malic acid)
$(b) C_{6}H_{12}O_{6}$ (Glucose)
$(c) C_{18}H_{36}O_{2}$ (Stearic acid)
$(d) \text{Succulents (night)}$

In germinating castor seeds,the $R.Q.$ is

The respiratory quotient of glucose is:
