GLYCOENOLYSIS

Page 2: Glycogenolysis

GLYCOENOLYSIS

• Break down of glycogen into glucose• It takes place in liver ad muscles• Key enzyme is glycogen phosphorylase

Page 3: Glycogenolysis

Reactions

• Shortening of chains• Removal of branches• Glucose-1-phosphate to G-6-Phosphate

Page 5: Glycogenolysis

Other pathway

• Lysosomal degradation(alpha amylosis)• Gemma-amylosis

Page 6: Glycogenolysis

Regulation

• Activation of Phosphorylase• Activation of inhibitor-1• Role of calcium in glycogenolysis in muscles
