Correct Act as a catalysts in a chemical reactions of cells, interact with specific substrates like a lock and key, can lower the required activation energy for reaction in living organisms

Enzymes are the protein molecules that act as biological catalyst, which speed up the rate of chemical reaction by lowering the activation energy of the chemical reaction which are required to carry out the chemical reactions.

Enzymes are specific in nature, which means they have a specific shape and only a specific substrate will fit into its active site and carry out the reactions.

All the biochemical reactions which are occurring inside the body require enzyme, without enzyme the rate of biochemical reaction would be much slower as compared to the reactions taking place in presence of enzyme.

Example: Lipase:- An enzyme which found in living organism which help in the digestion and processing of lipid, fats and oils.
