1 Membrane Transport Chapter 11

2 Transcellular transport of glucose

3 The Na + - K + pump is an ATPase

4 Response of red blood cells to changes in osmolarity of extra cellular fluids

5 Distribution of phospholipids and glycolipids in the lipid bilayer of human red blood cells

6 Few Ions are required to cause a large change in membrane potential

7 Electrochemical gradient vs. membrane potential Can work additively or against each other

8 Selectivity of a K + channel
