In what way could voltage-gated sodium channels be affected in excitatory neurons which would increase the likelihood of the neuron firing an action potential? (one correct answer)
a. The inactivation gate is slower to close.
b. The channel takes longer to reset to its original position (‘ready state’).
c. The channel is activated at a more negative membrane potential.
d. The channel has a lower permeability to Na+ compared to normal.
e. Any of the above mechanisms could make the cell more likely to fire an action potential.
