Answer 1

The correct option is D As energy provider for metabolsim

Proteins are responsible for the development of hairs, skin, wool, and nails in our body. Meat, eggs, and fish are some of the rich food sources of proteins. Enzymes are proteins made up of amino acids and acts as biological catalysts in our body. However, glucose serves the purpose of energy provider for metabolism which is not a protein.
