Protein is the building block of the cells and the body needs protein for growth and development of the individual organism.
Proteins help in regulating cell process for example hormones and enzymes respectively help in all metabolic and biochemical reactions of the body.
These macromolecules also provide movement as they are also present in muscles in the form of thick and thin filament also known as myosin and actin.
Thus, the correct answer is - providing structure, regulating cell processes, and creating movement.
