What are enzymes? The definition : enzyme |ˈenzīm| noun Biochemistry a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. An enzyme can break and build molecules. Enzymes speed up chemical reactions. Enzymes are protein molecules, made up of long chains folded to produce a special shape called the Active sites.

How they work The Enzyme The Substrate Other molecules, called substrates fit into the active site and then the reaction takes place. When the substrate enters the active site, depending on what type of enzyme it is (breaker, builder) it will either break the substrate into two or fit two and fuse them together. The Enzyme The Substrate

Animation Step 1: The Substrate enters the active site of the enzyme.

Animation Step 2: Once fit in the enzyme it will begin to break the enzyme down into two (breaker enzyme).

Animation Step 3: When the reaction is complete, the substrate will break into two. (breaker enzyme) As you can see, it has split to two now

Animation Step 4: After the reaction is complete, the two split pieces exit the Enzyme and leave
