Question

Which of the following target cells to increase metabolism? (Choose two)

Answer 1

Answer:

Hormones that act on the target cells to increase metabolism are Triiodothyronine (T₃) and Thyroxine (T₄).

Explanation:

The hormones triiodothyronine (T₃) and thyroxine (T₄) are the active forms of thyroid hormone, responsible for increasing cell metabolism.

Both T₃ and T₄are produced by the thyroid gland, in response to the pituitary hormone TSH. T₄ is more abundant but less powerful than T₃

Thyroid hormones are responsible for controlling cell metabolism, since their increase determines an increase in metabolism, and their deficiency slows it down.

The other options are not correct because:

• Thyrotropin Releasing Hormone (TRH) is produced by the hypothalamus to activate the production of TSH in the pituitary gland.
• Thyroid Stimulating Hormone (TSH) is a pituitary hormone in charge of activating the production of T₃ and T₄ in the thyroid.
• Adrenocorticotropic Hormone (ACTH) is produced by the pituitary gland to stimulate the production of hormones in the adrenal cortex.
