flows through the leaky channels?
That’s right but only during passive charging events. If an excitable cell gets charged enough it will trigger voltage-gated channels and a completely new channel current takes place (i.e., the action potential). > When a biological membrane is being charged, is it correct to say that > the build up of charge will be slower than that only across leak channels > but higher than the build up of charge only across the lipid bilayer. The two currents happen simultaneously so you can’t separate the capacitive from the resistive potential in a real cell. As the lipid bilayer becomes charged, more current goes through the leaky channels. The potential that develops across the whole cell membrane is a combination of these currents (Text Fig. 5-12). > (1) In the lecture you said that as the positive charge (K+) inside the cell > increases, this increases the negative charge in the cell because more K+ > leaves.
