Define R.Q. (Respiratory quotient). Give R.Q., if respiratory substrate is oxalic acid, tripalmitin and glucose.

Explanation

**Step-by-Step Solution:**

1. **Definition of R.Q. (Respiratory Quotient):**
- The Respiratory Quotient (RQ) is defined as the ratio of the volume of carbon dioxide (CO2) produced to the volume of oxygen (O2) consumed during respiration. It can be mathematically expressed as:
\[ RQ = \frac{\text{Volume of CO2 evolved}}{\text{Volume of O2 consumed}} \]
