Study Notes
Gap Junctions
- Gap junctions allow for the exchange of ions, metabolites, and signaling molecules between adjacent cells.
- Connexins are the proteins that make up the connexons in gap junctions.
- Tightly packed connexons create a channel or pore in gap junctions, allowing for direct communication between cells.
