BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Among the organic macromolecules, enzymes belong in the category of proteins. Proteins are distinct from carbohydrates, nucleic acids, and lipids in that a protein is made of amino acids.

Detailed explanation-2: -An enzyme is an organic molecule (usually a protein) that catalyzes a cellular reaction.

Detailed explanation-3: -Enzyme molecules are a class of polypeptides whose function in an organism is chiefly determined by their shape.

Detailed explanation-4: -A protein is an organic molecule composed of amino acids linked by peptide bonds.

Detailed explanation-5: -Enzymes are proteins, and they make a biochemical reaction more likely to proceed by lowering the activation energy of the reaction, thereby making these reactions proceed thousands or even millions of times faster than they would without a catalyst.
