Glycogenolysis

Question 1

Glycogen —–(E)—–P?

Answer 1

Glycogen—(glycogen phosphorylase)—-(glucose-1-phosphate)

(this enzyme is adding a phosphate)

Question 2

Glucose-1-phosphate—(E)—(P)?

Answer 2

G-1-P—–(phosphoglucomutase)—–glucose-6-phosphate

Question 3

glucose-6-phosphate–(E)—(P)?

Answer 3

glucose-6-phosphate–(glucose-6-phosphatase)—GLUCOSE

(this enzyme removes a phosphate)

Question 4

Image of glycogenolysis

Answer 4

Question 5

How can we convert glycogen to lactate?

Answer 5

• it can be done via glycogenolysis
• via G-6-P through glycolysis—>pyruvate—>via fermentation—->lactate

Question 6

What is glycogen made up of & what linkages are they made up of?

Answer 6

• made up of several glucose subunits bound together by α-1,4 glycosidic linkages
