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 indicate 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.

**Cell type B (transport protein mutant)**

| Time | IN [Na+] | OUT [Na+] | IN [ATP] | IN [Glu] | OUT [Glu] |
|------|----------|-----------|----------|----------|-----------|
| 0    | 150mM    | 15mM      | 200mM    | 5mM      | 200mM     |
| 10 ms| 40mM     | 125mM     | 70mM     | 5mM      | 200mM     |
| 20 ms| 40mM     | 125mM     | 70mM     | 5mM      | 200mM     |

**Q4.** Now, analyze a similar data set for cell type **B** above. Add an arrow labelled with 1° to indicate 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?
