Which of the following are not the effects of parathyroid hormone? 
A) Stimulates the process of bone resorption 
B) Decreases  level in the blood 
C) Reabsorption of   by renal tubules
D) Decreases the absorption of digested food 
E) Increases metabolism of carbohydrates

Choose the correct answer from the options given below.

Parathyroid hormone (PTH) increases the Ca2+ levels in the blood. PTH acts on bones and stimulates the process of bone resorption (dissolution/ demineralisation). PTH also stimulates reabsorption of Ca2+ by the renal tubules and increases Ca2+ absorption from the digested food. It is, thus, clear that PTH is a hypercalcemic hormone, i.e., it increases the blood Ca2+ levels. Along with TCT, it plays a significant role in calcium balance in the body.
