In the axon of a nerve cell,
A. the voltage-dependent conductance of the voltage-gated potassium channel has a faster time course than the voltage-dependent conductance of the voltage-gated sodium channel.
B. there is a net flux of potassium ions into the cell just after the maximum membrane voltage of the action potential.
C. the voltage-dependent conductance of the voltage-gated potassium channel increases as membrane voltage increases.
