Q.

RQ for protein is

1. 0.5

2. 0.7-0.9

3. 1

4. 1.4

Q.

Define RQ. What is its value for fats?

Q.

The hydrogen donor for purple and green sulphur bacteria is

1. H₂SO₄

2. HCl

3. H₂S

4. H₂O

Q.

When fats are the respiratory substrate, the value of RQ would be

1. More than 1.0

2. Approx. 1.0

3. Approx. 0.7

4. None of the above

Q. If RQ is less than 1.0 in a respiratory metabolism, it would mean that ___.

1. Carbohydrates are used as a respiratory substrate
2. Organic acids are used as respiratory substrate
3. Oxidation of the respiratory substrate consumed more oxygen than the $C{O}_2$ released
4. Oxidation of the respiratory substrate consumed less oxygen than the $C{O}_2$ released

Q. What happens to the respiration rate when a plant is transferred from water to salt solution?

1. Its respiration rate increases
2. Salt solution will have no effect on respiration
3. Respiration rate will first increase and then decrease
4. Its respiration rate decreases

Q.

Assertion (A): RQ value of fats and proteins is less than one

Reason (R): Fats and proteins consume more oxygen than carbohydrates do, during their oxidation

1. Both A $\&$ B are true and R explain A
2. Both A $\&$ B are true and R does not explain A
3. A is true and B is false
4. Both A $\&$ B are false

Q. A mixture containing equal quantities of germinating maize and groundnut seeds are taken. The RQ of this mixture would be _____.
