Now, cell number one produces hemichannel number one, and cell number two produces hemichannel number two, and then they connect them to form that gap junction. And so that's the final difference between these voltage gated and ligandgate on channels and gap junctions. Now, what exactly? Well, actually, before we examine the functionality of these gap junctions, let's discuss how these gap junctions are actually regulated by ourselves. Because just like voltage gated and ligan gate on channels have to be regulated for the proper functionality of the cells, these gap junctions too have to be regulated. And there are four methods by which we can actually close off these gap junctions.
