Ouabain is a chemical used on poison arrows in Africa. It works by inhibiting the sodium-potassium pump. What effect does this chemical have on an action potential?

Question

Quizplus · Accepted Answer

Ouabain inhibits the sodium-potassium pump, which is crucial for maintaining the resting membrane potential by regulating the concentration of sodium and potassium ions inside and outside the cell. This pump does not directly cause action potentials but is essential for resetting the ion gradient after an action potential, thus indirectly affecting the cell's ability to generate subsequent action potentials over time.
