Consider a time when the membrane voltage of a SA node cell in the heart is at its minimum value (near -80 mv). At this time,

A. all the voltage-gated calcium channels will be open.

B. the membrane voltage in the SA node cell will be less than the threshold voltage for the action potential in the SA node cell.

C. the conductance of the channels that carry the F-current (also called IF) will be high when compared to the conductance of these channels at the peak of the action potential.
