Best Answer

Enzymes are proteins which act as catalysts and allow complex chemical reactions to occur rapidly. Without enzymes, reactions would not occur quickly enough to allow cells to function effectively. For example, people who are lactose intolerant do not produce enough of the enzymes which break down lactose and therefore cannot digest lactose properly.
