Ions Can Move Across the Plasma Membrane in Which of the Following

Question

Ions can move across the plasma membrane in which of the following ways?
A) through voltage-gated channels as in the action potential
B) through passive or leak channels
C) by ATP-dependent ion pumps like the sodium-potassium exchange pump
D) through chemically gated channels as in neuromuscular transmission
E) All of the answers are correct.

Accepted Answer

All of the given options are correct. Ions can move across the plasma membrane through voltage-gated channels during an action potential, passive or leak channels, ATP-dependent ion pumps like the sodium-potassium exchange pump, and chemically gated channels as in neuromuscular transmission.
