Detailed explanation-1: -Proteins are a class of macromolecules that perform a diverse range of functions for the cell. They help in metabolism by acting as enzymes, carriers, or hormones, and provide structural support. The building blocks of proteins (monomers) are amino acids.

Detailed explanation-2: -Proteins. Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes.

Detailed explanation-3: -Proteins are extremely important. They are large, complex molecules that are used for structural support, storage, to transport substances, and as enzymes. They are a sophisticated, diverse group of molecules, and yet they are all polymers of just 20 amino acids.

Detailed explanation-4: -Protein: Provide structural support, transport, enzymes, movement, defense.

Detailed explanation-5: -The functions of proteins are very diverse because there are 20 different chemically distinct amino acids that form long chains, and the amino acids can be in any order.
