Question

What types of stimuli cause ion channels to open? When they open, will ions flow in or out of the cell?

Answer 1

Ion channels can open in response to electrical or chemical signals. When ion channels open, ions flow into or out of the cell.

Step-by-step explanation:

Ion channels can open in response to different types of stimuli, such as electrical or chemical signals. Some types of stimuli that can cause ion channels to open include voltage changes, chemical binding, and physical deformation of the cell membrane. When ion channels open, ions will flow into or out of the cell depending on the concentration gradient and the electrical potential across the membrane.
