Theyare opened either by the binding of ligands or by changes inelectric potential across the membrane. They are openmost of the time Which of the following statements about ion channels istrue? The rate oftransport is slow compared to the rate of transport via carrierproteins. They requireATP. Theyare opened either by the binding of ligands or by changes inelectric potential across the membrane. They are openmost of the timeIon channels are poreforming proteins that help to establish and control the smallvoltage gradient across the plasma membrane of all livingcells by allowing the flow of ions down their electrochemicalgradient. The ion channels areclassified based on the opening and closing of channels. Voltage-gated ion channelsopen and close depending on the voltage gradient across the plasmamembrane. The ligand-gated channelsopen or close depending on the binding of ligands to thechannel.
Hope you are satisfiedwith the answer. Which of the following statements about ion channels istrue? The rate oftransport is slow compared to the rate of transport via carrierproteins. They requireATP. Theyare opened either by the binding of ligands or by changes inelectric potential across the membrane. They are openmost of the time
