Why does the lack of glucose 6-phosphatase activity in the brain and muscle make good physiological sense?
Glucose 6-phosphatase allows cells to trap glucose in the cell; however, these tissues primarily rely on noncarbohydrate energy sources.
Glucose 6-phosphatase allows cells to generate glucose through gluconeogenesis; however, gluconeogenesis only takes place in the liver.
Glucose 6-phosphatase provides glucose 6-phosphate for glycogen synthesis; however, these tissues do not need glycogen.
Glucose 6-phosphatase allows cells to release glucose into the blood; however, these tissues should never release glucose.
