How do enzymes work to speed up reactions in the body?

Enzymes speed up chemical reactions by lowering activation rates. In general, the lower amount of activation energy that a potential reaction has, the faster the rate of reaction will be. Enzymes change shape during the reaction process, which allows them to efficiently reduce activation rates. read more

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. read more

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism. read more

Best Answer: Enzymes speed up reactions in your body by lowering the activation energy, or the initial energy input necessary for most chemical reactions to occur. read more
