WebAn excitatory postsynaptic potential (EPSP) occurs when sodium channels open in response to a stimulus. The electrochemical gradient drives sodium to rush into the cell. When sodium brings its positive charge into the cell, the cell’s membrane potential becomes more positive, or depolarizes. Web19. Opening of sodium gates typically leads to A repolarization of the plasma membrane back to resting membrane potential (RMP) B hyperpolarization of the plasma membrane, more negative than RMP. coepolarization of the plasma membrane, away from RMP. D. drifting of plasma membrane voltage toward a more negative value . E. all of the above 20.

WebFigure 12.5.2 – Ligand-Gated Channels: When the ligand, in this case the neurotransmitter acetylcholine, binds to a specific location on the extracellular surface of the channel protein, the pore opens to allow select ions through. The ions, in this case, are cations of sodium, calcium, and potassium. WebVoltage-gated sodium channels have two gates (gate m and gate h), while the potassium channel only has one (gate n). Gate m (the activation gate) is normally closed, and opens when the cell starts to get more positive. Gate h (the deactivation gate) is normally open, and swings shut when the cells gets too positive.
