Glycogeness Flashcards
1
Q
whats glycogenesis
A
making glycogen from G-6-P
2
Q
where does glycogenesis occur
A
cytosol of muscle/liver cells. `
3
Q
very first reaction?
A
G-6-P G-1-P
4
Q
second reaction?
A
G-1-P + UTP –UDP glucose pyrophosphorylase–> UDP glucose + 2Pi
5
Q
describe initiation
A
Glycogenin catalyses reaction of UDP glucose to UDP and glucose. glucose attaches to glycogenin.
Glycogen synthase is added to glycogenin
Glycogenin catalyses addition of first 7-8 glucose molecules
6
Q
describe elongation.
A
glycogen synthase catalyses the addition of the rest UDP glucose molecules
7
Q
describe branching
A
glycogen branching enzyme transfers hexa/heptasaccharides to C-6
8
Q
describe glycogen synthase
A
scaffold
primer for glycogen synthase
