Question

Channels that open and close in response to vibration and pressure:

• A. Leakage channels
• B. Ligand gated channels
• C. Mechanical gated channels
• D. Voltage gated channels

Answer 1

The correct option is C Mechanical gated channels

Mechanical gated channels open or close in response to mechanical stimulation such as vibration, touch, pressure or tissue stretching.
Gates of leakage channels randomly alternate between open and closed positions.
A wide variety of chemical ligands- including neurotransmitters, hormones and particular ions can open or close ligand gated channels.
Voltage gated channels open and close in response to a change in the membrane potential.
