for energy
A. Control and balance levels of calcium and phosphate in blood and tissue fluids
The correct answer is A. Control and balance levels of calcium and phosphate in blood and tissue fluids.
To arrive at this answer, we can break down the question and analyze the key terms.
First, we need to understand what the parathyroid gland is responsible for. The parathyroid gland is a small endocrine gland located in the neck, near the thyroid gland. It is primarily responsible for regulating the levels of calcium and phosphate in the blood and tissue fluids of the body.
Next, we evaluate the given options:
A. Control and balance levels of calcium and phosphate in blood and tissue fluids - This aligns with the function of the parathyroid gland.
B. Secretes androgen hormones, including testosterone and estrogen - Androgen hormones are primarily secreted by the testes and estrogen hormones are secreted by the ovaries. This does not apply to the parathyroid gland.
C. Involved in regulating the body's sugar levels - The regulation of sugar levels is primarily controlled by the pancreas, which produces insulin and glucagon, not the parathyroid gland.
D. Regulates the sleep-wake cycle - The sleep-wake cycle is regulated by the pineal gland, which secretes melatonin, not the parathyroid gland.
E. Secretes chemicals that dramatically alter energy levels - The alteration of energy levels is primarily controlled by hormones such as adrenaline (epinephrine) and noradrenaline (norepinephrine), which are secreted by the adrenal glands, not the parathyroid gland.
F. Produces hormones that control the rate at which cells burn fuels from food - This aligns with the function of the parathyroid gland.
Based on this analysis, we can conclude that the correct answer is A. Control and balance levels of calcium and phosphate in blood and tissue fluids.
