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 ... More »

Enzymes either make certain reactions possible or speed up a reaction that would take too long otherwise. An enzyme works using the lock-and-key method. The substrate is the substance acted on by the enzyme. A substrate ... More »

Enzymes speed up the rates of reactions within the body. An enzyme acts by binding to a substrate, the substance that will be acted on by the enzyme. When the substrate binds to the enzyme, the reaction takes place. More »

Enzymes are special proteins that control the speed of certain functions in the body; without them, chemical reactions would take place too slowly to keep a person alive. There are many different types of enzymes in the ... More »
