Which of these processes can be commonly associated with an ion being transported across a cell membrane?
A) A change in voltage across the cell membrane
B) A change in the state of a ligand-gated channel
C) All options listed here are correct
D) Rapid entry/exit across the membrane relative to a carrier
E) A change in the state of a mechanically gated channel

Question

Quizplus · Accepted Answer

All the options listed (A, B, D, E) describe mechanisms or phenomena that can be associated with the transport of ions across a cell membrane. Changes in voltage can affect voltage-gated channels, ligand-gated channels respond to specific chemical signals, mechanically gated channels respond to physical forces, and ions can indeed move rapidly across membranes relative to carriers, which is a characteristic of facilitated diffusion or active transport processes.
