Explanation / Answer

Answer is B

that is it directly promote cell division.

growth hormone is secreted by anterior pituitary gland. it consist of 190 amino acids. It has different anatomical and physiological effects on body.

i. it plays an important role in embryonic and fetal development

ii. it stimulates the bone growth by secreting insulin like growth factor-I(IGF-I) from liver.

iii. improves the function of liver

iv. it also stimulate the synthesis of proteins in the muscles.

Growth hormone is not directly involved in the cell division. The cell division in cell proliferation is carried by presence of Zinc molecules. Pituitary is rich in zinc molecules. zinc also regulates the hormonal regulation of cell division, especially groth hormone. The increased or decreased level of zinc influence the cell proliferation. So the growth hormone is not directly stimulate the cell proliferation.
