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⁺

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

If RQ is 0.6 in a respiratory metabolism, it would mean that

1. Carbohydrates are used as respiratory material

2. Organic acids are used as respiratory substrate

3. The oxidation of the respiratory substrate consumed more oxygen than the amount of CO${}_2$ released

4. The oxidation of respiratory substrate consumed less oxygen than the amount of CO2 released

Respiratory Quotient

The value of respiratory Quotient actually depends upon

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

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 (RQ) value of tripalmitin is:

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

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