1. Proteins

2. A Little Review… Monomer = Amino Acids Elements = CHON
Varied Functions
Help muscles and movement
Help the immune system
Cell transport
Biochemical reactions… ENZYMES!

3. Enzymes: Proteins at Work
Speed up biological processes without increasing temperature
Increase reaction rate (catalyst)
Bind to a substrate at active site
Substrate = Reactants
Specific enzymes act on specific substrates: lock and key
When done, products release from enzyme
Enzyme can be used more than once

4. Enzymes Substrate Complex
