Vedclass · Answer

(A) The Respiratory Quotient $(R.Q.)$ is defined as the ratio of the volume of $CO_2$ evolved to the volume of $O_2$ consumed during respiration.For carbohydrates,the $R.Q.$ is $1$. For fatty acids,the $R.Q.$ is typically less than $1$ (usually around $0.7$) because they are highly reduced and require more oxygen for oxidation.However,among the options provided,none of the fatty acids (Oleic,Stearic,Palmitic) have an $R.Q.$ of $1$. Acetic acid is a simple organic acid that can be fully oxidized in the respiratory pathway,and in specific metabolic contexts,it can exhibit an $R.Q.$ of $1$ because its chemical structure $(CH_3COOH)$ allows for an equal ratio of $CO_2$ production to $O_2$ consumption $(CH_3COOH + 2O_2 \rightarrow 2CO_2 + 2H_2O)$.Therefore,Acetic acid is the correct answer.

For which of the following fatty acids is the value of $R.Q.$ equal to $1$?
