They play huge role in organisms, every living organism needs proteins.
enzymatic role ( they build enzymes which lower an activation energy in reactions and increase reaction speed)
hormonal role (they build hormons)
structural role (for example keratin)
transport role ( for example hemoglobin)
energetic role ( for example aleurone grains in plant cells or they are used to gain energy in human organism when it's out of lipids and carbohydrates)
Proteins play vital roles in organisms, including enzymatic functions, structural support, transportation of substances, hormonal regulation, immune response, and energy provision. They are essential for various biological processes that keep organisms functioning. Understanding these roles illustrates the significance of proteins in everyday life and health.
