NEET BIOLOGY

Detailed explanation-1: -Nucleic Acids These molecules contain the genetic code, which has all the information necessary to build the body. The basic unit is called a nucleotide, which is composed of a sugar-phosphate backbone attached to one of four nitrogenous bases; cytosine, guanine, adenine or thymine.

Detailed explanation-2: -Answer and Explanation: The class of biomolecule that is mostly used as an energy storage molecule are polysaccharides. Specifically in some cells the storage molecule at the most basic level is glucose. In larger organisms the storage molecule for humans is glycogen which is used as a glucose storage.

Detailed explanation-3: -There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s mass.

Detailed explanation-4: -Lipids are the main component of the cell membrane and are often referred to as fats. Proteins serve as pumps or channels moving materials in and out of the cell membrane. Carbohydrates are compounds that form sugars and are made of carbon, hydrogen, and oxygen.
