Glucogenesis Steps

(after meal)

1.Glucose -->(enzyme: glucokinase!) to G-6-PO4

2. --> G-1-PO4 (mustase moves it to stop it from going to glycolysis)

3. UTP gives it another PO4...which brings it to the primer

4.  Glycogen synthase liberate the UDP if primer is present

5. A branching enzyme makes a branch to store it as glycogen!

Glycogenolysis (Breaking it down to glucose)

1. Glycogen is debranched by glycan transfase enzyme.  Now it's a straight chain of G-1-PO4

2. -->G-6-P04 

3. If in muscle cell, the G-6-PO4 goes to glycolysis for energy.  If in liver cell PO4 is taken off to supply glucose to body cell.

Blood sugar is now in steady state: 80-110 mg/L

Epinephrine and Glucagon. 

Glycogenesis (ate carbs and want to make glycogen):::Glycogen Synthase -P is turned ON while phosphorylase -P is OFF

IS RECIPROCAL!! 

Converting non-CHO's (ie lipids and proteins) to glucose to control blood glucose if on a low/no carb diet or while sleeping.

Occurs in liver and kidney
