The 'respiratory quotient' of fat is

  • 0.7

  • 1.5

  • 2

Solution

A.

0.7

Respiratory Quotient (RQ) is the ratio of CO2 evolved and O2 absorbed during respiration.

RQ = Amount of CO2 evolvedAmount of O2 absorbed

The RQ of fat will always be less than one. Hence, 0.7 is the correct answer.
