In succulent plants like Opuntia , the RQ value will be:
1 Infinity
2 Zero
3 Less than 1
4 More than 1
Explanation:
The respiratory quotient, is defined as the volume of carbon dioxide released over the volume of oxygen absorbed during respiration and is denoted as RQ. In some succulent plants like Opuntia, Bryophyllum, etc carbohydrates are incompletely oxidised to organic acids in dark without the evolution of , hence the value of RQ remains zero. \[\begin{array}{*{20}{c}} {{\rm{2}}{{\rm{C}}_{\rm{6}}}{{\rm{H}}_{{\rm{12}}}}{{\rm{O}}_{\rm{6}}}{\rm{ + 3}}{{\rm{O}}_{\rm{2}}}}\\ {{\rm{Glucose}}} \end{array} \to \begin{array}{*{20}{c}} {{\rm{3}}{{\rm{C}}_{\rm{4}}}{{\rm{H}}_{\rm{6}}}{{\rm{O}}_{\rm{5}}}}\\ {{\rm{Malic}}\;{\rm{acid}}} \end{array}{\rm{ + 3}}{{\rm{H}}_{\rm{2}}}{\rm{O}}\] \({\rm{RQ = }}\frac{{{\rm{Vol}}{\rm{.}}\;{\rm{of}}\;{\rm{C}}{{\rm{O}}_{\rm{2}}}}}{{{\rm{Vol}}{\rm{.}}\;{\rm{of}}\;{{\rm{O}}_{\rm{2}}}}}{\rm{ = }}\frac{{\rm{O}}}{{\rm{3}}}{\rm{ = 0}}\)

Statement A : The ratio of the volume of \(\mathrm{CO}_{2}\) evolved to the volume of \(\mathrm{O}_{2}\) consumed in respiration is called the respiratory quotient (RQ) Statement B : The RQ depends upon the type of respiratory substrate used during respiration
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
Both the statements are correct.

If volume of \(\mathrm{CO}_{2}\) liberated during respiration is more than the volume of \(\mathrm{O}_{2}\) used, the respiratory substrate will be
1 Carbohydrate
2 Fat
3 Protein
4 Organic acid
Explanation:
Organic acids have more volume of \(\mathrm{CO}_{2}\) liberated during respiration than the volume of \(\mathrm{O}_{2}\) used.

Assertion : When carbohydrates are used as substrate and completely oxidised, R.Q is 1 Reason : When proteins are used in respiration as substrate the R.Q is greater than 1.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
R.Q (respiratory quotient) depends on the type of respiratory substrate used during respiration. When carbohydrates is used as substrate and is completely oxidised the R.Q will be 1 , because equal amount of \(\mathrm{CO}_{2}\) and \(\mathrm{O}_{2}\) are evolved and consumed. When proteins are used as respiratory substrate, R.Q will be around 0.9 (which bis less than 1).
