All living things are kept
All living things are kept alive by doing chemical reactions. In fact, some estimate that your body performs around 500 quadrillion reactions per second. That’s a lot!
These reactions are what keep you alive, and are done by special molecules called enzymes! So, enzymes are super important! NO enzymes, no life!
So, what are enzymes? Enzymes are PROTEINS that speed up chemical reactions to make them happen.
Here’s how they work:
The Pac-Man looking thing on the left is an enzyme. Notice that it has a little triangular region (that looks like its mouth). That is called the active site and it is where the reaction happens.
On the right we have a molecule in the shape of a triangle. It is called the SUBSTRATE. This is the molecule that will undergo a chemical reaction.
Notice that the substrate fits perfectly into the active site of the enzyme (just like a puzzle piece). Each enzyme can only work on specific substrates, to do specific chemical reactions, so we say that enzymes are specific. When the substrate enters the active site, the enzyme weakens the chemical bonds in the substrate, causing the chemical reaction to happen. The molecules that are produced by the reaction are called PRODUCTS.
The enzyme is not altered by this reaction and can be used again and again.
Although this animation showed an enzyme breaking down a substrate, there are other enzymes that do the opposite. They take substrates and join them together to make a larger product.
