NEET BIOLOGY

Detailed explanation-1: -Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins. In our previous section on network polymers, we mentioned vulcanized rubber and pectin. Vulcanized rubber is a synthetic (man-made) polymer, while pectin is an example of a natural polymer.

Detailed explanation-2: -All of the biomolecules that make up our cells are made up of strings of monomers. For example, proteins are made up of strings of amino acids and nucleic acids are strings of nucleotides.. The term for a long string of monomers is a polymer. The biomolecules, proteins, carbohydrates and nucleic acids are all polymers.

Detailed explanation-3: -Polymers are molecules made from a large number of monomers joined together. Monosaccharides, amino acids and nucleotides are examples of monomers. A condensation reaction joins two molecules together with the formation of a chemical bond and involves the elimination of a molecule of water.

Detailed explanation-4: -A protein is usually a naturally occurring type of polyamide. This polymer consists of an amide group present in the backbone chain of the human body. Collagen– Collagen is one of the natural polymers and is a protein. It makes up the connective tissue present in the skin of human beings.

Detailed explanation-5: -A polymer is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms and are the basis of many minerals and man-made materials.
