[Answer] Which of the following allow the movement of potassium through the neuronal membrane?

Answer: leakage channels and voltage-gated potassium channels
Which of the following allow the movement of potassium through the neuronal membrane?

Sodium (Na +) and potassium ions inside and outside the cell are moved by a sodium potassium pump ensuring that electrochemical equilibrium remains unreached to allow the cell to maintain a state of resting membrane potential.

G protein-gated ion channels are primarily found in C NS neurons and atrial myocytes and affect the flow of potassium (K +) calcium (Ca 2+) sodium (Na +) and chloride (Cl −) across the plasma membrane. Types of G Protein-gated ion channels Potassium channels

Leak potassium channels allow potassium to flow through the membrane in response to the disparity in concentrations of potassium inside (high concentration) and outside the cell (low). The loss of positive(+) charges of the potassium (K+) ions from the inside of the cell results in a negative potential there compared to the extracellular surface …

Voltage-gated ion channels are a class of transmembrane proteins that form ion channels that are activated by changes in the electrical membrane potential near the channel. The membr…
