You Are What You Eat! So What Are Enzymes?

Did you know that without enzymes, it would take your body 7 years to digest a hamburger?

So What are Enzymes?

1. They are a biological catalyst (something that speeds up a chemical reaction)
2. Enzymes make a reaction go faster by lowering the activation energy
3. The reactant is the substrate that the enzyme reacts with, forming the enzyme-substrate complex
4. The product is then released
5. An enzyme can be used over and over again for the same reaction
