Which of the following will occur when an excitatory postsynaptic potential (EPSP)is being generated on the dendritic membrane?
A) Sodium gates will open first, then close as potassium gates open.
B) A single type of channel will open, permitting simultaneous flow of sodium and potassium.
C) Specific sodium gates will open.
D) Specific potassium gates will open.

A single type of channel opens during an excitatory postsynaptic potential (EPSP), allowing both sodium (Na+) and potassium (K+) ions to flow simultaneously. This dual ion movement is crucial for depolarizing the postsynaptic membrane, making the neuron more likely to fire an action potential.
