Monosaccharide Transport Proteins

Medical Condition:
Monosaccharide Transport Proteins

Membrane transport proteins which bind glucose and sodium ions and enter the cell together. The sodium ions are then pumped out of the cell by a sodium potassium ATPase. The rate and extent of the sugar transport depends on the sodium ion concentration. Inhibitors of the monosaccharide transport system are phlorizin, cytochalasin B, and inhibitors of the sodium potassium ATPase system. Insulin increases the rate of monosaccharide transport across the membrane into the cell.
