Describe how enzymes affect chemical reactions and explain why this makes enzymes important to living things

Enzymes are known as catalysts in a chemical reaction, as they can reduce the time it takes for the reaction to occur by breaking things down. Enzymes are important to living things, because they can be found throughout the body to aid in things like digestion and fighting illnesses. A good example would be putting a Ritz cracker in your mouth and letting it dissolve. This happens because your mouth is full of enzymes that help break food down before entering the digestive system. Hope this helps! :)
