Question

Optogenetics is a powerful tool that uses light to control the activity of specific neurons. These neurons contain artificially introduced light-gated ion channels. A number of different light-gated channels with different ion specificities have been either found in nature (such as the sodium-specific channelrhodopsin, originally found in green algae) or produced via genetic engineering (the production of a chloride ion-specific form of channelrhodopsin). There are also light-gated ion channels specific for potassium or calcium. Sort each light-activated channel type based on whether activation of this channel will tend to depolarize cells or not.

Answer 1

Answer:

Explanation:

Matching the appropriate type of light-activated channels to its effect on the depolarization of the nerve cells :-

Promote depolarization Inhibit depolarization

Sodium ions channel      Chloride ion channel

Calcium ion channel       Potassium ion channel
