3.Facilitate diffusion: Membrane transport protein mediated movement down the gradient ② OUTSIDE OF CELL Transport protein ① shifts to altemative ③ Glucose binds conformation Glucose is to binding site released to the open to outside inside and protein returns to its original Glucose conformation INSIDE OF CELL Glucose Glucose transporter (GluT1) The carrier protein,the Glucose transporter(GLUT1 )in the erythrocyte PM,alter conformation to facilitate the transport of glucose.
