Respiratory quotient $(R.Q.)$ is defined as:

When the respiratory substrate is ......,the volume of $CO_2$ evolved is more than the volume of $O_2$ consumed.

The respiratory quotient $(RQ)$ or respiratory ratio is defined as:

In succulent plants like $Opuntia$, the $RQ$ value will be

What is the $R.Q.$ of the given reaction?
$2(C_{51}H_{98}O_6) + 145 O_2 \rightarrow 102 CO_2 + 98 H_2O + \text{energy}$

$2 (C_{52} H_{89} O_{12}) + 145 O_2 \rightarrow 102 CO_2 + 89 H_2O + \text{energy}$.
To make the equation true, what should be placed in the reactant side instead of $2 (C_{52} H_{89} O_{12})$?
