A
Phosphoglucomutase
2
Q
Glucose 1 phosphate to UDPGlc
A
UDPGlc pyrophosphorylase
3
Q
UDPGlc to 1-4 glycosyl units
A
Glycogen synthase
4
Q
1-4 glycosyl units to glycogen
A
Debranching enzyme
5
Q
Insulin
A
Decreases cAMP therefore promoting glycogenesis
6
Q
Glucagon and epinephrine
A
Increase cAMP and promote glycogenolysis
7
Q
CAMP is hydrolyzed by ____________
A
Phosphodiesterase
8
Q
Phosphorylase kinase b
A
Inactive when phosphorylated
Transfers phosphate group to phosphorylase a
9
Q
Protein phosphatase 1 (PFK-1)
A
Dephosphorylates phosphorylase kinase a
10
Q
Phosphorylase A
A
Activates by phosphorylation
Starts glycogenolysis
11
Q
Glycogen synthase A
A
Active by dephosphorylation
Promotes glycogenesis
12
Q
