1

Competitive inhibitor

Higher Km
Same Vmax

2

Uncompetitive

Lower Km
Lower Vmax

3

Noncompetitive

Same Km
lower Vmax

4

pH dependence of enzymes is due to:

The presence of ionizable R groups

5

Competitive

Irreversibly binds to substrate active site
-Can be overcome by increase in substrate concentration

6

Uncompetitive

inhibitor binds only to enzyme substrate complex

7

Noncompetitive

Inhibitor and substrate bind to enzyme at different binding sites

8

Catalytic Triad

Chymotrypsin active site
ASP, HIS, SER
Asp stabilizes the + charge for His
His makes Ser a stronger nucleophile
Ser is a nucleophile that will attack peptide bond

9

Pure hemoglobine

Hyperbolic
-binds to oxygen more tightly

10

Sucrose

glucose+fructose

11

Lactose

glucose+galactose

12

Maltose

glucose+glucose
