उत्तर
Growth hormone promotes growth of all the tissues and the metabolic process of the body. It influences the metabolism of carbohydrates, proteins, and lipids. It increases the rate of protein biosynthesis in the cells.
It stimulates chondrogenesis (cartilage formation), osteogenesis (bone formation) and helps in the retention of minerals like nitrogen, potassium, phosphorus, sodium, etc in the body. It increases the release of fatty acid from adipose tissue and decreases the rate of glucose utilization for energy by the cells. The hyposecretion of growth hormones causes dwarfism in children.
