Remember the functions of the protein: are in charge of structure of red blood cells, keep the proper functioning of antibodies resisting infection, regulate the enzymes and hormones for growth, and they repair body tissue.

Answer:

The correct answer is providing structure, regulating cell processes and creating movement.

Proteins are large molecules consisting of one or more polypeptide chains. They perform many important functions in the body such as:

  • Structural base: they are the building blocks of the cell.
  • Movement: They help in locomotion of a cell. For example, actin and myosin present in muscle cells.
  • Hormones: Many hormones are protein in nature and help in the control and coordination of the body. For example, insulin and growth hormones are protein in nature.
  • Enzymes: Most of the enzymes are protein in nature. Enzymes are biological catalysts which regulate the biochemical reactions taking place in an organism.
  • Defense: Antibodies are protein in nature.
  • Transport: Proteins form channels across the plasma membrane which facilitate the transport of molecules across the membrane.

In contrast, DNA acts as the genetic material which forms the blueprints of an organism as well as the bases of heredity. They are transcribed into different types of RNA which together synthesize the proteins.
