Study Notes
Glucose 6-Phosphate Hydrolysis
- Glucose 6-phosphatase is the enzyme responsible for bypassing the irreversible hexokinase reaction during glucose 6-phosphate hydrolysis.
- Liver and kidney are the two organs that release free glucose from G-6-P.
- Glucose 6-phosphate translocase functions in transporting G-6-P across the ER membrane.
Glycogen Degradation
- Glucose 6-phosphatase is required for the final step of glycogen degradation.
- Glucose 6-phosphate translocase and glucose 6-phosphatase are needed for the final step of glycogen degradation.
Glycogen Storage Disease
- Type Ia glycogen storage disease is a disease caused by the lack of glucose 6-phosphatase.
- Consequences of lack of glucose 6-phosphatase include Type Ia glycogen storage disease.
Glucose 6-Phosphate Function
- Glucose 6-phosphate is involved in the step of glycogen degradation that releases free glucose.
- The function of glucose 6-phosphate is to release free glucose from G-6-P.
Proteins Required for Glucose 6-Phosphate Hydrolysis
- Glucose 6-phosphatase and glucose 6-phosphate translocase are the two proteins required for glucose 6-phosphate hydrolysis.
- Glucose 6-phosphatase and glucose 6-phosphate translocase are required for transporting G-6-P across the ER membrane and releasing free glucose in liver and kidney.
Cellular Location of Glucose 6-Phosphatase
- Glucose 6-phosphatase is found in liver and kidney cells.
Enzyme Function in Glycogen Synthesis
- Glucose 6-phosphate is not involved in glycogen synthesis, and the enzyme required for the first step in glycogen synthesis is not glucose 6-phosphatase.
