And check this question,
Glucose enters erythrocytes via a GLUT-1 uniporter. As the levels of glucose in the bloodstream decrease between mels, what happens to the glucose in the cells? Glucose remains in the cell because the GLUT-1 uniporters are gated and the gates close at low glucose concentrations Ob. Glucose remains in the cell because uniporters can only transport in one direction OGlucose remains in the cell because it has been phosphorylated and no longer has affinity for the GLUT-1 uniporter. O d. Glucose leaves the cell through the GLUT-1 uniporter, traveling down the new concentration gradient o a
Explanation / Answer
1) b. Glucose remains in the cell because uniports can only transport in one direction.
Glut-1 transportors maintain a minimum required level of glucose in the rbcs. Their numbers increase during low blood glucose levels and vice versa.
2)a) they are hydrophilic.
Since phosphate has negatively charged oxygen atoms they are charged and hence water loving (=hydrophilic)
