glucogenolysis

Question 1

Breakdown of dietary starch process

Answer 1

amylase breaks down nonreducing ends, cleaves 1,4 bonds
glucosidase cleaved branching ends, cleaves 1,6

Question 2

Where is glycogen stored?

Answer 2

In the liver and skeletal muscle

Question 3

what is the first step to glycogen breakdown?

Answer 3

glycogen phosphorylase eats nonreducing ends until 4 units from branch point, phosphorylus releases glucose 1 phosphate

Question 4

what is the second step to glycogen breakdown?

Answer 4

Branching enzyme(transferase) bits off remaining branched glycogen and adds to nonreducing end, leaving one glycogen. Glucosidase bites off last branched glycogen and releases it as glucose

Question 5

h\What is the third step in glycogen breakdown?

Answer 5

Phosphoglucomutase converts g1p to g6p

Question 6

What cofactor does glycogen phosphorylase use?

Answer 6

PLP, covalently found via schif base at lysin

Question 7

What allows for the phosphoglucomutase to do a phosphate change?

Answer 7

phosphorylated serine on the enzyme
