AIIMS 2019 Botany Amphibolic Pathways MCQ Question
Assertion: Respiratory pathway is considered as an amphibolic pathway
Reason: It involves both anabolism and catabolism.
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
The respiratory pathway is considered amphibolic because it serves dual roles in metabolism: it facilitates catabolic processes, such as the breakdown of glucose (C₆H₁₂O₆) to produce ATP, CO₂, and H₂O, while also supporting anabolic processes, such as the synthesis of biomolecules from intermediates generated during respiration. This dual functionality allows the pathway to integrate energy production and biosynthesis, making it essential for cellular metabolism. Other options are not relevant as they do not provide any alternative explanations or details regarding the amphibolic nature of the respiratory pathway.
