(Science: Biochemistry). A catalyst or a chemical produced by cells to generally speed up specific chemical reaction without changing the chemical reaction at the end of the reaction.upplement. Enzyme is usually a protein molecule with a characteristic sequence of amino acids that fold to produce a specific three-dimensional structure, which gives the molecule unique properties. Other molecule with catalytic activity is ribozyme, an enzyme made of RNA rather than protein.
Enzyme: Proteins that speeds up the rate of a chemical reaction in a living organism. An enzyme acts as catalyst for specific chemical reactions, converting a specific set of reactants (called substrates) into specific products.nzyme: Proteins that speeds up the rate of a chemical reaction in a living organism.
