Question

Thyroxine production is dependent on
A. Calcium
B. Zinc
C. Iodine
D. Carbon

Answer 1

Hint: The thyroid, also known as the thyroid gland, is an endocrine gland in the neck that consists of two paired lobes. A thin band of tissue called the thyroid isthmus connects the lower two-thirds of the lobes.

Complete answer:
Thyroxine is the primary hormone secreted by the thyroid gland into the bloodstream. It is important for digestion, heart and muscle function, brain growth, and bone maintenance.
Iodine and calcium are needed for thyroid hormone production. Cortisol's primary metabolic effect is gluconeogenesis. Iodine is a necessary component in the synthesis of thyroxine.
The thyroid gland's primary function is to produce hormones, T4 and T3, which are needed for the control of metabolic processes in the body. Iodine is the critical raw material since it accounts for 65 percent of the weight of T4. Iodine is absorbed and circulated as iodide after being consumed.
So, Thyroxine production is dependent on Iodine. So, option C is the correct answer.
Thyroxine is the primary hormone secreted by the thyroid gland into the bloodstream. It is important for digestion, heart and muscle function, brain growth, and bone maintenance.

So, option C is the correct answer.

Note:
A goitre is usually caused by an iodine deficiency or thyroid gland inflammation. Not all goitres show symptoms. While most goitres are painless, a large goitre can cause a cough and make it difficult to swallow or breathe.
