The membrane transport protein Na+-K+ ATPase carries both Na+ and K+ ions across the plasma membrane.Typically the concentration of K+ inside cells is about 30 times higher inside the cell than outside.The concentration of Na+ is about 20 times less inside the cell than outside.Based on this information,which statement below is false?

Question

Quizplus · Accepted Answer

Na+-K+ ATPase is not a symport, as it transports Na+ and K+ ions in opposite directions. It is an antiport. The other statements are true. Na+-K+ ATPase uses ATP hydrolysis to transport ions and can create a concentration gradient that serves as an energy source for other transport proteins. The transport process involves conformational changes in the protein.
