________ Channels Open or Close in Response to Physical Distortion

Question

________ channels open or close in response to physical distortion of the membrane surface.
A) Voltage-gated
B) Chemically gated
C) Active
D) Mechanically gated
E) Leak

Accepted Answer

Mechanically gated channels open or close in response to physical distortion of the membrane surface. Voltage-gated channels open or close in response to changes in membrane potential, chemically gated channels open or close in response to binding of a specific ligand, active channels are not a recognized type of ion channel, and leak channels are always open and allow for passive movement of ions across the membrane.
