Which chemical element is required by the thyroid gland for the synthesis of thyroid hormones?
A
Magnesium (Mg)
B
Calcium (Ca)
C
Iron (Fe)
D
Iodine (I)
Verified step by step guidance1
Understand the role of the thyroid gland: The thyroid gland is responsible for producing thyroid hormones, which regulate metabolism, growth, and development in the body.
Identify the key components of thyroid hormones: Thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3), are synthesized using iodine as a critical element.
Learn why iodine is essential: Iodine is incorporated into the structure of thyroid hormones. For example, thyroxine (T4) contains four iodine atoms, and triiodothyronine (T3) contains three iodine atoms.
Compare the options provided: Magnesium (Mg), Calcium (Ca), and Iron (Fe) are important for other biological functions but are not directly involved in the synthesis of thyroid hormones. Iodine (I) is the correct element required for this process.
Conclude the reasoning: The thyroid gland specifically requires iodine to synthesize thyroid hormones, making it the correct answer to the problem.
