Question

A value of RQ less than one means

• A. Carbohydrates are used as respiratory material.
• B. Organic acids are used as respiratory substances.
• C. Oxidation of respiratory substrate consume more O${}_2$ than CO${}_2$ released.
• D. Oxidation of respiratory substrate consume less O${}_2$ than CO${}_2$ released The reaction is anaerobic.

Answer 1

The correct option is C Oxidation of respiratory substrate consume more O${}_2$ than CO${}_2$ released.

When the RQ value is less than one for fats, as fats consume more oxygen for respiration than carbohydrates.

So the correct option is 'Oxidation of respiratory substrate consume more O2 than CO2 released.'
