d) To store and release energy in the form of glucose

Sagot :

Answer: B) To secrete substances such as enzymes and sweat through ducts to external surfaces or cavities

Explanation: Exocrine glands are glands with ducts that secrete enzymes, sweat, and other substances directly onto bodily surfaces. Examples of exocrine glands include sweat glands (which secrete sweat onto your skin), salivary glands (which secrete saliva onto the surfaces of your mouth), and mammary glands (which excrete milk from the chest)

Choice A is incorrect because its description is referring to endocrine glands. Endocrine glands are glands that release hormones directly into the bloodstream, not exocrine glands. Examples of endocrine glands include the pancreas and thyroid gland, which regulate sugar and calcium levels in the blood respectively.

Choice C is incorrect. The thyroid and parathyroid glands are primarily responsible for controlling bodily metabolic rate, and both of these glands are endocrine glands, not exocrine glands.

Choice D is incorrect. As mentioned previously, the pancreas is the organ responsible for controlling sugar levels (and by extension energy levels) in the blood by releasing insulin and glucagon. The pancreas too, is an endocrine gland, not an exocrine gland.
