Question

R.Q for fatty substance/fat is

• A. Unity
• B. Less than one
• C. Greater than one
• D. Zero.

Answer 1

The correct option is B Less than one

Respiratory quotient or R.Q is the ratio of carbon dioxide consumed to oxygen evolved.

Carbohydrates are the most efficient compounds because the amount of carbon dioxide consumes and oxygen evolved is almost the same, therefore the RQ is one.

For the fatty substances RQ is less than 1 and for proteins, this is 0.9.

So, the correct option is 'less than 1'
