What's the difference between channel and track?

Channel


Definition:

  • (n.) The hollow bed where a stream of water runs or may run.
  • (n.) The deeper part of a river, harbor, strait, etc., where the main current flows, or which affords the best and safest passage for vessels.

  • (v. t.) To form a channel in; to cut or wear a channel or channels in; to groove.
  • (v. t.) To course through or over, as in a channel.

  • (15) The following model is suggested: exogenous ATP interacts with a membrane receptor in the presence of Ca2+, a cascade of events occurs which mobilizes intracellular calcium, thereby increasing the cytosolic free Ca2+ concentration which consequently opens the calcium-activated K+ channels, which then leads to a change in membrane potential.
