Connexon scheme

The connexon is the pore-forming complex made up of six connexin molecules. Two connexons form a gap junction channel that crosses the membranes of two adjacent cells and thus connects the cytoplasms of two adjacent cells. Several hundred gap junction channels together form the gap junction , which enables the exchange of ions and small molecules between neighboring cells.

The transport equation:

Low molecular compound (cytoplasm cell 1) Low molecular compound (cytoplasm cell 2)
