The correct answer is option A) (b), (d), and (e) only.
Parathyroid hormone (PTH) is a hormone secreted by the parathyroid glands, which are located in the neck. PTH plays a crucial role in maintaining calcium (Ca2+) homeostasis in the body. Its main effects include:
(a) Stimulates the process of bone resorption: PTH stimulates osteoclasts, which are bone cells responsible for breaking down bone tissue. This leads to the release of calcium from the bones into the bloodstream.
(b) Decreases Ca2+ level in blood: This statement is incorrect. PTH actually increases the level of Ca2+ in the blood. It does so by stimulating bone resorption, increasing the reabsorption of calcium from the renal tubules, and promoting the production of active vitamin D, which enhances intestinal absorption of calcium.
(c) Reabsorption of Ca2+ by renal tubules: PTH acts on the kidneys to increase the reabsorption of calcium from the renal tubules. This helps to conserve calcium in the body and prevent its loss through urine.
(d) Decreases the absorption of Ca2+ from digested food: This statement is correct. PTH indirectly decreases the absorption of calcium from the digestive system by promoting the production of active vitamin D. Active vitamin D enhances the absorption of calcium from the intestines.
(e) Increases metabolism of carbohydrates: This statement is correct. PTH can increase the metabolism of carbohydrates by stimulating glycolysis, which is the breakdown of glucose to produce energy.
In summary, the effects of parathyroid hormone (PTH) include stimulating bone resorption, increasing the reabsorption of calcium by renal tubules, decreasing the absorption of calcium from digested food, and increasing the metabolism of carbohydrates. Therefore, the correct answer is option A) (b), (d), and (e) only.

Which of the following a re not the effects of Parathyroid hormone ?(a...
Concept:
- Parathyroid glands are located at the back of the thyroid glands.
- They secrete a hormone known as parathyroid hormone or parathormone (PTH)
- It regulates the level of calcium in the blood.
Explanation:
- PTH increases the level of calcium in the blood when it’s too low.
- It increases bone resorption by increasing the activity of osteoclasts and thus adding more calcium to blood.
- It also increases the reabsorption of calcium ions from renal tubules and digested food.
- PTH also decreases the metabolism of carbohydrates.
So, the correct answer is option a.
