Q. When carbohydrates are the respiratory substrates the Respiratory Quotient (R.Q.) becomes:

BVP MedicalBVP Medical 2006

Solution:

When carbohydrates are the respiratory substrate, the R.Q. become unity or one. It is dear from the equation given below $ {{C}_{6}}{{H}_{12}}{{O}_{6}}+6{{O}_{2}}\to 6C{{o}_{2}}+6{{H}_{2}}O $ $ R.Q.=\frac{C{{O}_{2}}evolved}{{{O}_{2}}taken}=\frac{6}{6}=1 $
