This gate only opens when the channel activates. Nearer the outward side of the pore is another narrow region called the selectivity filter.

Web16 okt. 2012 · To summarize, we started by explaining what ion channels are and what is their role in transmission of information to the brain. We learned about two groups of temperature sensitive ion channels, and the mechanism of how they work. We learned why hot chocolate is sweeter then cold chocolate, and we learned how ion channels are … WebIon channels are integral membrane proteins that contain pathways through which ions can flow. By shifting between closed and open conformational states ('gating' process), they control passive ion flow through the plasma membrane. Channels can be gated by membrane potential, or specific ligands, or other agents, such as mechanical stimuli.
