Which of the following components of the ring structure of chlorophyll helps in maintaining the ribosome structure?

Correct option is A

Ans. (a)
Sol. Magnesium (Mg) is a key component of the ring structure of chlorophyll and plays an essential role in maintaining ribosome structure. Magnesium stabilizes ribosomes and is necessary for protein synthesis in plants. In addition, it is crucial for photosynthesis, as it forms the central ion in the chlorophyll molecule, allowing it to capture light energy.
Explanation of each option:
· (a) Magnesium – Correct answer. It is part of the chlorophyll structure and also helps in maintaining ribosome integrity.
· (b) Iron – Incorrect, as iron is essential for electron transport in photosynthesis but does not directly maintain ribosome structure.
· (c) Sulphur – Incorrect, as sulphur is a component of amino acids and proteins but not chlorophyll.
· (d) Potassium – Incorrect, as potassium regulates stomatal function and enzyme activation but is not part of chlorophyll or ribosome structure.
