Question

Which phrase best describes the need for ion channels?
ions must be able to interact with the charged regions of the cell membrane
o ions need to be sheltered from interacting with the charged regions of the cell membrane
Oso nutrients may enter the cell
O so nutrients may exit the cell

Answer 1

ions must be able to interact with the charged regions of the cell membrane best describe the need for ion channels.

What is Ion channels?

Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient. The resulting ionic current, generated by the movement of charged ions through membrane channels, can be measured by patch-clamp methods.

Answer 2

Ion channels must be able to interact with the charged regions of the cell membrane so nutrients can enter the cell.

What are ion channels?

Ion channels are passages in the cell membrane that allow the passage of charged molecules such as

• Sodium: Na+
• Potassium: K+

Ions pass from one side to the other of the cell according to the electrochemical gradient. In other words, they go from a place with high concentration to one of low concentration. But to do this, they need to interact with the charged regions of the membrane, which are the ion channels.

Ions channels are one of the ways that nutrients enter the cell.
