What is an enzyme?

• A biological catalyst, a molecule that lowers the activation energy of reactions and increases reaction rates.

• A small, inorganic molecule that prevents reactions from occurring in the cell.

• A molecule made up of monosaccharides that provides energy to cells.

• A type of protein that tags pathogens for destruction by the immune system.
