What is an enzyme?
Enzymes are as specific category of protein which are used to catalyze reactions within living things. A catalysis speeds up reaction times for chemical reactions. These are reactions that would occur naturally, eventually. With enzymes, these reactions occur much quicker. This is the difference between getting energy from your lunch in 30 minutes versus 5 hours.
Enzymes have various parts:
The enzyme contains an active site.

How do enzymes work?
Enzymes work on the same principles as hydrolysis or condensation reactions.(See 2.1 for more information)
Reactions occur with enough energy to allow the reaction to occur. (See Activation energy in 8.1)
