Which element is needed by the thyroid gland to produce thyroxine hormone?
Sodium
Iodine
Calcium
Potassium
Potassium
Iodine is an essential trace element required by the thyroid gland to synthesize thyroxine (T4тАЛ) and triiodothyronine (T3тАЛ) hormones, which regulate the body's basal metabolic rate, growth, and development.
Iodine is an essential trace element required by the thyroid gland to synthesize thyroxine (T4тАЛ) and triiodothyronine (T3тАЛ) hormones, which regulate the body's basal metabolic rate, growth, and development.
Just like a car engine needs a specific key or fuel additive to start and run smoothly, the thyroid gland needs iodine as the crucial building block to fire up and produce the metabolic hormone thyroxine.
I-O-D-I-N-E = 'I On Diet Is Needed Every day' for thyroid health.
T4тАЛ тАФ Thyroxine (Tetraiodothyronine, containing 4 iodine atoms)
T3тАЛ тАФ Triiodothyronine (containing 3 iodine atoms)
Dietary iodide is actively taken up by thyroid follicular cells via sodium-iodide symporters (NIS). Within the colloid of the thyroid follicle, iodide is oxidized to iodine and incorporated into tyrosine residues of thyroglobulin to form monoiodotyrosine (MIT) and diiodotyrosine (DIT), which subsequently couple to form the thyroid hormones thyroxine (T4тАЛ) and triiodothyronine (T3тАЛ).
Iodine is a crucial micronutrient required for the synthesis of thyroid hormones.
Thyroxine controls the basal metabolic rate, protein synthesis, and sensitivity to other hormones.
Iodine deficiency leads to hypothyroidism, commonly resulting in a condition known as Goiter.
Iodized salt is widely used as a public health measure to prevent iodine deficiency disorders (IDD).
Regulates normal physical and mental growth and development.
Maintains optimal basal metabolic rate (BMR).
Prevention of endemic goiter and cretinism through iodization programs.
Regulation of energy metabolism in human physiology.
Sodium is an electrolyte important for fluid balance and nerve transmission, not specifically required by the thyroid for hormone synthesis.
Calcium is vital for bone mineralization, muscle contraction, and blood clotting.
Potassium is an essential intracellular electrolyte responsible for maintaining membrane potential.
D is correct тАФ Iodine is an essential element required by the thyroid gland to produce the thyroxine hormone.
In competitive exams like RRB and SSC, questions regarding vitamin deficiencies (e.g., Scurvy, Beriberi) and mineral deficiencies (e.g., Goiter due to Iodine, Anemia due to Iron) are frequently asked.
