An EPSP: A)is a direct result of the opening of ligand-gated channels permeable to both Na⁺ and K⁺ ions. B)is a direct result of the opening of voltage-gated channels permeable to both Na⁺ and K⁺ ions. C)stabilizes the membrane to remain at its resting potential. D)opens voltage-gated Ca²⁺ channels in the presynaptic membrane. E)occurs when voltage-gated Cl- channels open in a postsynaptic cell membrane.

Question

Quizplus · Accepted Answer

EPSP (Excitatory postsynaptic potential) is a direct result of the opening of ligand-gated channels that allow the entry of cations (Na+ and K+) into the postsynaptic cell, leading to a depolarization of the membrane potential.
