- NEET 2023EasyEssential Mineral ElementsQ1Which micronutrient is required for splitting of water molecule during photosynthesis?
[NEET 2023]- AMolybdenum
- BMagnesium
- CCopper
- DManganese
Show answer & solution
Correct answer: (D)
Manganese plays a major role in the splitting of water to liberate oxygen during photosynthesis. Copper is essential for the overall metabolism in plants.
Molybdenum is included in nitrogen metabolism.
Magnesium activates several enzymes involved in photosynthesis and respiration. - NEET 2023EasyDeficiency Symptoms and ToxicityQ2Which of the following mineral ion is not remobilized in plants? [NEET 2023 mpr]
- APotassium
- BCalcium
- CNitrogen
- DPhosphorus
Show answer & solution
Correct answer: (B)
Mineral remobilization is a process in which nutrients are transported from older tissues (like mature leaves) to newer ones (like young leaves or developing seeds). Most mineral ions like potassium, nitrogen, and phosphorus are remobilized in plants. However, calcium, once incorporated into plant tissue, generally remains immobile. Therefore,
calcium is considered a mineral ion that is not remobilized in plants. - NEET 2022MediumMetabolism of NitrogenQ3Which of the following protects nitrogenase inside the root nodule of a leguminous plant?
[NEET Re-2022]- AGlutamate dehydrogenase
- BCatalase
- Cleg haemoglobin
- DTransaminase
Show answer & solution
Correct answer: (C)
The enzyme Nitrogenase is highly sensitive to the molecular oxygen square It acquires anaerobic condition. The nodules have adaptations that ensure that the enzyme is protected from oxygen. To protect these enzymes, the nodule contains an oxygen scavenger called leghaemoglobin.
