$R.Q.$ is represented by

The $R.Q.$ (Respiratory quotient) of $C_{39}H_{72}O_6$ is

The $RQ$ (Respiratory Quotient) of oxalic acid $(COOH)_2$ is:

Considering the following chemical equation,guess the nature of the respiratory substrate:
$\begin{array}{l}2 C_{51}H_{98}O_{6} + 145 O_{2} \longrightarrow 102 CO_{2} + 98 H_{2}O + \text{Energy}\end{array}$

The $R.Q.$ (Respiratory Quotient) is zero when the respiratory substrate is:

The respiratory quotient during cellular respiration would depend on the
