Why are the Na+/K+ pumps needed? Select all that are true.
The pumps are the only means by which ions are able to move from one side of the membrane to the other.
The movement of ions produces the necessary metabolic energy required of all cells
The extrusion of Na+ is required for osmotic reasons, to prevent the undue osmosis of water into cells.
These pumps contribute to the potential difference across the plasma membrane
The steep Na+ gradient produced by the pumps is needed for secondary active transport
