Which is not a use or function of protein? forms enzymes and hormones forms transport channel in cell membrane forms structural proteins in the body quick energy

Proteins are essential macromolecules in the body that perform a variety of functions. They form enzymes and hormones, which are crucial for regulating various physiological processes. Proteins also form transport channels in the cell membrane, allowing specific molecules to pass through. Additionally, proteins serve as structural components in the body, such as collagen in the skin and keratin in the hair. However, proteins are not a primary source of quick energy. Carbohydrates, such as glucose, are the body's preferred source of quick energy. Therefore, the statement "quick energy" is not a use or function of protein.
