Ralle von Biologischen Membranen
- Protection, solation
- Compartimentalization
- Communication, interface with external environment
- Gates, water & solutes transport
Pores
Non-gated channels = channels that are always open
Connexon

The Overton Rule
• The boundary of cells is mostly constituted of a lipidic material
• Non-lipophilic substances (incl. water) must use specific pathways
CHIP 28 - Aquaporin 1
Channel-like Integral Membrane Protein
-> Extremely abundant in RBCs (redbloodcells)
-> billions of water moleclues can cross the pore per second
