If fat is oxidized as a sole substrate, the RQ value equals 1?
That's Correct!
It's Wrong!
When fat is oxidized as a sole substrate, the RQ value is not equal to 1. The respiratory quotient (RQ) is the ratio of carbon dioxide produced to oxygen consumed during metabolism. When fat is the only substrate being oxidized, the RQ value is less than 1 because the oxidation of fat produces more carbon dioxide relative to the amount of oxygen consumed. Therefore, the correct answer is false.
