WebThe two strands of DNA are held together by hydrogen bonds between the paired bases. As a result of its involvement in a chemical reaction, an enzyme is unchanged by the reactants or products. An enzyme is a macromolecule that acts as a catalyst, a chemical agent that speeds up a reaction without being consumed or changed by the earlier reaction.
