Glycogen Phosphorylase Control In The Liver
Cards in this deck (9)
- 1Low Glucose- Protein Phosphatase A is bound toGlycogen phosphorylase- affinity is high
- 2Glucose Low- Glyocgen Phophorylase isPhosphorylated (hidden and cannot be removed)
- 3Glucose Rises- Glucose StabilisesTense form of protein Glycogen phosphorylase A
- 4Glucose Rises- Glycogen Phosphorylase isDephosphorylated by protein phosphatase 1
- 5Glucose High- Protein Phosphatase 1Glycogen synthase is dephosphorylated, and glycogen synthase continues
- 6Glucose High- Glycogen PhosphorylaseGlucose binds to it, causing its tense, inactive form
- 7Why only in the liver?GLUT2 transporters
- 8GLUT2 Glucose AffinityLow, so it's only active when blood glucose is high and its a good time to store it
- 9Why Glucokinase?High glucose Km, so it only functions when blood glucose levels are high
