Glucose enters erythrocytes via a GLUT-1 uniporter. As the levels of glucose in the bloodstream decrease between meals, what happens to the glucose in the cells?

#Unit 2. Cellular Organization

Glucose leaves the cell through the GLUT-1 uniporter, traveling down the new concentration gradient.
Glucose remains in the cell because uniporters can only transport in one direction.
Glucose remains in the cell because the GLUT-1 uniporters are gated and the gates close at low glucose concentrations.
Glucose remains in the cell because it has been phosphorylated and no longer has affinity for the GLUT-1 uniporter.
