AIIMS 2019 Botany Enzymes Match the Following Question

Option B is correct because it accurately matches the components based on their respective roles in biological processes: A corresponds to the process of cellular respiration (i), B to photosynthesis (iii), and C to the nitrogen cycle (ii). Other options are incorrect as they misalign the processes with their functions; for instance, option A incorrectly pairs cellular respiration with photosynthesis, leading to confusion about the distinct biochemical pathways involved in energy transformation and nutrient cycling. Understanding these processes is crucial, as cellular respiration involves the conversion of glucose (C₆H₁₂O₆) and O₂ into CO₂ and H₂O, while photosynthesis transforms CO₂ and H₂O into glucose and O₂, highlighting the interdependence of these cycles in ecosystems.
