The value of respiratory Quotient actually depends upon

The RQ of a substrate is found to be 0.9 what would be that substrate?

RQ of tripalmitin is

1. $\frac{6{\mathrm{CO}}_2}{6{\mathrm{O}}_2}$

2. $\frac{102{\mathrm{CO}}_2}{145{\mathrm{O}}_2}$

3. $\frac{2{\mathrm{CO}}_2}{\mathrm{Zero} {\mathrm{O}}_2}$

4. $\frac{4{\mathrm{CO}}_2}{1{\mathrm{O}}_2}$

RQ (Respiratory Quotient) is defined as

(1) $\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved} = \mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}$

(2) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}}{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved}}$

(3) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{evolved}}{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{consumed}}$

(4) $\frac{\mathrm{Volume} \mathrm{of} {\mathrm{O}}_2 \mathrm{evolved}}{\mathrm{Volume} \mathrm{of} {\mathrm{CO}}_2 \mathrm{consumed}}$

When (i) are used in respiration the RQ is (ii). Select the correct option for (i) and (ii) that make the sentence a correct sense.
1. (i) Carbohydrates, (ii) > 1
2. (i) Proteins, (ii) > 1
3. (i) Fats, (ii) < 1
4. (i) Malic acid, (ii) < 1

Respiratory Quotient

For the substrate Glucose, how many Oxygen are used and how many Carbon-dioxide are evolved?

When proteins are used as respiratory substrates, the respiratory quotient would be about:
1. 1.2
2. 1.0
3. 0.9
4. 0.7

When tripalmitin is used as substrate in respiration, the value of RQ is found to be less than one because

Select the correct statement

1. ATP formation occurs both in chloroplast and mitochondria

2. RQ of protein is 1.5

3. RQ of fatty acid is more than one

4. Cytochrome a₃ has both Fe³⁺ and Fe²⁺
