The diffusion/exchange rate of a protein can be measured by photobleaching techniques such as
FRAP. When there is protein exchange (i.e. if the protein is mobile), fluorescence recovery in the
bleached region occurs, as shown in the figure above.
The graphs below show the fluorescence measurement of an area in the cell before and after
bleaching for protein 1 and protein 2. Which protein has lower mobility?

Which of the following explains why sodium ions cannot go through a potassium channel.
A sodium ion is much bigger than a potassium ion
The arrangement of a specific group of partially negative oxygen atoms in the structure of potassium
channel makes it highly energetically unfavorable for sodium ions to go through.
Sodium ions cause the closing of a potassium channel
none of the above
