Is water evaporating a chemical change?
Interesting. Can you tell me more about enzymes and how they affect chemical reactions?
Enzymes are biological catalysts that speed up the rate of chemical reactions in the body without being consumed in the process. They work by lowering the activation energy needed for a reaction to occur, making it easier for molecules to collide and react. Different enzymes are specific to different reactions, and they each have an optimal temperature and pH range in which they function best.
