E) All of the answers are correct.

Ion channels are proteins located in the membrane that allow ions to pass through the channel pore. Ion channels can be classified (by what opens and closes the channels) into few groups:

• Voltage-gated channels-open and close in response to membrane potential

Examples: Voltage-gated proton channels, Voltage-gated sodium channels, Voltage-gated potassium channels

• Ligand-gated (neurotransmitter) or ionotropic receptors (ligand binds to extracellular domain of the receptor

Examples: "nicotinic" Acetylcholine receptor, ionotropic glutamate-gated receptors

• Lipid-gated- lipid molecules bind to the  transmembrane domain of the channel

Example: Inward-rectifier potassium channels

• Light-gated channels-like rhodopsin channel that is directly opened by photons

• Mechanosensitive (e.g. stretch, pressure) ion channels.

Answer: The correct answer is option C

FACILITATED DIFFUSION.

Explanation: FACILITATED DIFFUSION is a form of passive transport,it is the process by which substances(molecules) move from a region of higher concentration to a region if lower concentration along their concentration gradient through the help of a membrane transporter forming a pore or channel(Protein).

Facilitated diffusion dies not require high energy to occur since a concentration gradient is involved.
