The primary function of growth hormone is to promote growth and development. This hormone is produced by the pituitary gland and plays a crucial role during childhood and adolescence, facilitating the growth of bones and tissues. It stimulates the production and synthesis of proteins, which are vital for cell growth and multiplication. In addition to its role in physical growth, growth hormone also has metabolic effects that influence how the body uses fats and carbohydrates for energy.

While growth hormone does contribute to metabolic processes, its foremost purpose lies in its ability to drive growth and development, making it essential for normal physical stature. The other options, although important bodily functions, do not encapsulate the primary role of growth hormone. For example, while growth hormone can have an indirect effect on metabolism and may influence blood sugar levels, its main function remains centered around promoting growth.
