NEET BIOLOGY

Detailed explanation-1: -Carbohydrates, nucleic acids, and proteins are often found as long polymers in nature. Because of their polymeric nature and their large (sometimes huge!) size, they are classified as macromolecules, big (macro-) molecules made through the joining of smaller subunits.

Detailed explanation-2: -Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules-large molecules necessary for life that are built from smaller organic molecules.

Detailed explanation-3: -Most macromolecules are polymers, which are long chains of subunits called monomers. These subunits are often very similar to each other, and for all the diversity of polymers (and living things in general) there are only about 40-50 common monomers. Making and breaking polymers.

Detailed explanation-4: -Large biological molecules. Called macromolecules by some authorities, the large biological molecules inside every living organism are essential for the biological processes that sustain life-like growth, cell development, and reproduction.

Detailed explanation-5: -A macromolecule is a very large molecule important to biophysical processes, such as a protein or nucleic acid. It is composed of thousands of covalently bonded atoms. Many macromolecules are polymers of smaller molecules called monomers.
