CHANNEL A single protein or protein complex that transversethe lipid bilayer of cell membrane and form a channel to facilitatethe movement of ions through membrane according to theirelectromagnetic gradient is called a channelA channel may be openor gatedCARRIERS A carrier is a protein that carry substances from oneside of a biological membrane to the otherA carrier typically hasa binding site which will only bind to substances they are supposedto carryPUMPS An ion transporter ion pump is a trans membraneprotein that moves ions across the plasma membrane against theirconcentration gradient through active transportIt means they arepumping ions from areas of higher to lower concentrationsLEAK CHANNELS Ion channels that are always open andresponsible for the resting membrane potentialThe leak channelsallow Na and K to move See Answer
