NEET BIOLOGY

Detailed explanation-1: -Proteins are found in all living organisms and are composed of molecules called amino acids. Each amino acid contains four elements they are hydrogen, oxygen, nitrogen and carbon and in certain cases may also contain sulfur.

Detailed explanation-2: -Carbon can be found in all four of the biomolecules (carbohydrates, lipids, proteins, and nucleic acids). In biomolecules, carbon is usually the most abundant element. In carbohydrates, carbon atoms form ring-like structures that are central to the molecule. In lipids, carbohydrates form long chains.

Detailed explanation-3: -Answer and Explanation: A biomolecule that is made up of carbon, hydrogen, oxygen, and nitrogen is a protein molecule. The building blocks of proteins are subunits called amino acids.

Detailed explanation-4: -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-5: -Proteins are the polymers of amino acids and have C, H, O, N and S.
