Now, analyze a similar data set for cell type B above. Add an arrow labelled with 1° to indicated where primary active transport occurred. Add an arrow labelled with 2° to indicate where secondary active transport occurred (if it occurs).

Q3. On the data table for cell type A and graphs on the previous page, use arrows labelled with 1° to
indicated where primary active transport occurred (if it occurs). Add arrow(s) labelled with 2° to indicate
where secondary active transport occurred (if it occurs). On your diagram and written description also
distinguish between primary versus secondary active transport.

Q4. Now, analyze a similar data set for cell type B above. Add an arrow labelled with 1° to indicated
where primary active transport occurred. Add an arrow labelled with 2° to indicate where secondary
active transport occurred (if it occurs).
Q5. What is not occurring in Cell B (mutant) compared to Cell A (non mutant) ?
Therefore, what do you conclude about the normal role of this transport protein?
