exists and is an alternate of. Merge this question into. Split and merge into it. Answer by Pkchoober. Confidence votes 73. In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
â¢ Enzymes are proteins that act as catalysts. Catalysts increase the rate of a chemical reaction without being consume by the reaction. Enzymes are not altered during a reaction and therefore they can be reused again and again.â¢ An enzyme speeds up a reaction by lowing the reactionâs activation energy.ll reactions require some energy to get started (activation energy). Enzymes lower the activation energy they do not provide activation energy. All chemical reactions require activation energy (Ea). Without enzymes reaction in cells would be slow and take a very long time.â¢ Enzymes are specific for certain reactions.
