How do ion channels differ?
How do ion channels differ? Channels differ with respect to the ion they let pass (for example, Na+, K+, Cl−), the ways in which they may be regulated, the number of subunits of which they are composed and other aspects of structure. What are the 4 ion channels? Ion channels can be voltage-sensitive, ligand-gated, or mechanically-gated in nature. Ligand-gated ion channels open when a chemical ligand such as a neurotransmitter binds to the protein. Voltage channels open and close in response to changes in membrane potential. Do ion channels have specificity? 1. Ion channels can be highly selective for particular...
