5. Enzymes (catalysts)
Enzyme level does not change. What would increase the rate?
1. More substrate
2. More enzymes
3. Increase temperature
4.Agltate
5. Optimize pH
B. Temperature-

C. pH-
D. Allosteric Enyzmes- have a 2nd bonding site for a chemical that will alter the active site of the enzyme. 2 types:
1.Repression- happens when the molecule that bonds to the allosteric site makes the active site less likely to bond the substrate. Feedback Inhibition- excess product acts as the represses molecule.
2. Activation- happens when the molecule that bonds to the allosteric site makes the active site more likely to bond the substrate. Vitamins
