BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -Proteins are macromolecules formed by amino acids Proteins are large size molecules (macromolecules), polymers of structural units called amino acids.

Detailed explanation-3: -Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.

Detailed explanation-4: -The large molecules required for life built from smaller organic molecules are called biological macromolecules. There are four major biological macromolecules classes: carbohydrates, lipids, proteins, and nucleic acids.

Detailed explanation-5: -Proteins are macromolecular polypeptides-i.e., very large molecules (macromolecules) composed of many peptide-bonded amino acids. Most of the common ones contain more than 100 amino acids linked to each other in a long peptide chain.
