Amino acid refers to a fundamental building block of the proteins comprising an amino group and a carboxyl group.  

Any component that enhances a chemical reaction without itself getting consumed in the reaction is known as the catalyst.

DNA or deoxyribonucleic acid refers to a composite molecule comprising the genetic code.  

Enzyme refers to a molecule of protein, which is unique to accelerate a particular chemical reaction in a biological system.  

Nucleic acid refers to a sequence of phosphates, sugars, and nitrogenous bases, that is, DNA and RNA.  

A protein refers to a large and composite organic molecule comprising a huge number of amino acids associated together by the peptide bonds.  

RNA or ribonucleic acid refers to a nucleic acid, which takes part in the production of proteins.  

A compound, which takes part in a chemical reaction, and is chemically modified by the reaction is termed as a substrate.
