BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

Detailed explanation-2: -Nitrogen is in all amino acids and nucleotides, and therefore in all proteins and nucleic acids. Nitrogen is also a major component of the chitin that makes up the cell walls of fungi and the exoskeletons of aquatic insects and crustaceans.

Detailed explanation-3: -Proteins contains nitrogen. They are large biological molecules or macromolecules, consisting of one or more long chains of amino acids (organic compounds composed of amine (−NH2) and carboxylic acid(−COOH)).

Detailed explanation-4: -Yes, nitrogen is an essential element for proteins. Nitrogen is act as a molecular building block of proteins and is also a fundamental component of amino acids. The protein needs nitrogen because of amino acids. There would be no protein, without amino acids and without protein, there are no enzymes.
