bio 600 exam 2 Flashcards
1
Q
Competitive inhibitor
A
Higher Km
Same Vmax
2
Q
Uncompetitive
A
Lower Km
Lower Vmax
3
Q
Noncompetitive
A
Same Km
lower Vmax
4
Q
pH dependence of enzymes is due to:
A
The presence of ionizable R groups
5
Q
Competitive
A
Irreversibly binds to substrate active site
-Can be overcome by increase in substrate concentration
6
Q
Uncompetitive
A
inhibitor binds only to enzyme substrate complex
7
Q
Noncompetitive
A
Inhibitor and substrate bind to enzyme at different binding sites
8
Q
Catalytic Triad
A
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
Q
Pure hemoglobine
A
Hyperbolic
-binds to oxygen more tightly
10
Q
Sucrose
A
glucose+fructose
11
Q
Lactose
A
glucose+galactose
12
Q
Maltose
A
glucose+glucose
