Channel A is a Na channel, channel B is a K channel and channel
C is a Cl channel. The relative abundance of these three channels
in the example cell membrane is 10,000(A), 500(B) and 10(C).

Assume that channel E is actually the Na K ATPase and channels
A-C are as described above. You have these cells in a tissue
culture dish, growing in your lab. You treat the cells with
oaubain, which is glycoside that inhibits the Na K ATPase. How
would that affect the movement of Na through channel A?

A. it would increase the flow into the cell

B. It would decrease flow into the cell

C. it wouldn’t effect flow through channel A

WHY?
