Question

Define RQ. What is its significance?

Answer 1

Answer:

Respiratory Quotient

Explanation:

RQ=Volume of CO2 evolved divided by volume of O2 consumed in a respiratory reaction and is generally based on the kind of substrate used for reaction.

C6H12O6 +6O2---------- 6CO2 +6H2O

( glucose)

RQ=6(CO2 evolved) divided by 6(O2 consumed)

Therefore RQ=1

Answer 2

Dear Student,

◆ Respiratory quotient -

• It is ratio of carbon dioxide produced to oxygen consumed during cellular respiration of food.

● Significance of respiratory quotient -

• It depends on type of food substrate and type of respiration.

1. RQ for carbohydrates is 1.
2. RQ for fats is about 0.7.
3. RQ for proteins is about 0.5-0.9.
4. RQ for green leafy vegetables is zero.
5. RQ for anaerobic respiration is infinity.

Thanks dear...
