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 (Respiratory Quotient) value is less than 1, not equal to 1. The RQ value represents the ratio of carbon dioxide produced to oxygen consumed during metabolism. Since fat oxidation requires more oxygen compared to the amount of carbon dioxide produced, the RQ value is less than 1. Therefore, the statement "If fat is oxidized as a sole substrate, the RQ value equals 1" is false.
