Question

Which of the following correctly rank the steps in erythrocyte glucose transport by GLUT1? I. Glucose binding results in a conformational change, opening the binding site on the opposite side of the membrane II. Glucose binds to the transporter on one side of the membrane III. The transporter reverts to initial conformation IV. The glucose disassociates

Answer 1

Answer:

Following are the correctly rank steps:  

1. The binding of glucose takes place with the transporter on one side of the membrane.  

2. The binding of glucose leads to a conformational change, which opens the site of binding on the contrary side of the membrane.  

3. The dissociation of glucose takes place.  

4. The transporter moves back to the beginning conformation.
