Up to 25% of a Cell's ATP Is Used to Run

Multiple Choice

Up to 25% of a cell's ATP is used to run sodium-potassium pumps. Without the resulting sodium and potassium gradients, neurons and muscles cannot fire properly.
-If a person is poisoned with cyanide,they cannot generate ATP,and die within a few minutes.In relation to the sodium-potassium pump,what specific impact would cyanide have on concentrations across the cell membrane?

A) Sodium and potassium concentrations would both be higher inside the cell.
B) Both sodium and potassium concentrations would become isotonic outside the cell.
C) Sodium concentration would be higher outside the cell, while potassium concentration would be higher inside the cell.
D) Sodium and potassium concentrations would both be higher outside the cell.
E) Both sodium and potassium concentrations would reach equilibrium conditions across the cell membrane.
