Question

Quizplus · Accepted Answer

Thyroid hormones, specifically thyroxine (T4) and triiodothyronine (T3), are important regulators of basal metabolic rate, which is the amount of energy the body uses at rest. This is because thyroid hormones increase the rate of cellular respiration, leading to an increase in energy consumption by cells.

Option B is false because thyroid hormones are stored in the thyroid gland and released in response to a signal from the pituitary gland.

Option C is false because thyroid hormones do not contain chromium or zinc as structural cofactors.

Option D is also false because thyroid hormones are not tropic, which means they do not stimulate the release of other hormones.
