Question

The resting membrane potential is dependent upon two important factors: 1) differences in sodium and potassium concentrations across the membrane (electrochemical gradients) and 2) differences in sodium and potassium membrane permeability. This activity will help you to review how the resting membrane potential of cells are generated and maintained. Use the Na+and K+ions to correctly complete each sentence about the resting membrane potential. Ions may be used more than once, or not at all. a) The concentration of ___ is higher inside than outside the cell. b) The concentration of ___ is higher outside than inside the cell. c) The membrane is more permeable to ___. d) The resting membrane potential is maintained by Na+-K+pumps that actively transport ___ into and ___ out of the cell.

Answer 1

Na+ K+ATPase is an an ion channel that helps in the transport of Na+ ion inside the cell and K+ ion outside the cell by active transport.

Step-by-step explanation:

The concentration of Na+ ion is higher inside the cell whereas b the concentration of K+ is higher outside the cell.cThe membrane is more permeable to K+ ion d The resting membrane potential maintained by Na+K+ pump that actively transport Na+ into and K+ out of the cell.
