Glucose binds to a site on the transporter that faces the cell's exterior. • 2. Glucose binding causes a conformational change that exposes the glucose to the cell interior. • 3. Glucose dissociates from the transporter. • 4. The transporter reverts to its original conformation. • What class of transporter is this Na+ glucose transporter? • 1. Two sodium ions bind to the 1 transporter. • 2. Glucose binds to the transporter. • 3. The transporter undergoes a conformational change. • 4. The glucose dissociates from the transporter, followed by the sodium. • Na+K+ Transport • 1. Three Na'+ ions bind. • 2. A phosphoryl group is transferred from ATP to Asp. • 3. The protein conformation changes and Na+ dissociates. • 4. Two extracellular K+ bind. • 5. The Asp phosphate group is hydrolyzed and P, is released. • 6. The protein conformation changes and K+ dissociates.
