Matching Nutrients to Biological Functions

This question involves matching specific nutrients from List I to their corresponding primary functions listed in List II.

Detailed Matching Breakdown

• Iron (I): This essential mineral is crucial for the synthesis of haemoglobin, the protein in red blood cells that carries oxygen. Therefore, Iron matches with C. Haemoglobin synthesis.
• Calcium (II): Calcium is vital for building and maintaining strong bones and teeth. Its role in bone health includes bone mineralization. Thus, Calcium matches with E. Bone mineralization.
• Iodine (III): Iodine is a key component of thyroid hormones, which regulate metabolism and are critical for normal brain development, especially in early life. Iodine matches with F. Brain development.
• Zinc (IV): Zinc plays a role in numerous bodily functions, including immune response and cell growth. It is also important for senses like taste and smell, contributing to normal taste acuity. Zinc matches with A. Normal taste acuity.
• Fluorine (V): Fluoride strengthens tooth enamel, making it more resistant to acid attacks from plaque and sugars, thereby ensuring the stability of teeth enamel and preventing cavities. Fluorine matches with D. Stability of teeth enamel.

Final Code Sequence

Based on the individual matchings:

• Iron (I) -> C
• Calcium (II) -> E
• Iodine (III) -> F
• Zinc (IV) -> A
• Fluorine (V) -> D

The correct code representing the sequence of functions for nutrients I to V is C E F A D.
