cells are constantly pumping ions in and out to maintain cell volume and ph. some of these ions include sodium (na ) and potassium (k ). these ions are moved against the concentration gradient by the na /k pump, a channel protein in the plasma membrane. which statement explains what will happen when a chemical is added to cells that prevents atp from functioning? responses the na /k pump will work more efficiently. the na, , /k, , pump will work more efficiently. the cells will not be able to undergo active transport. the cells will not be able to undergo active transport. the na /k pump will move too many ions across the membrane. the na, , /k, , pump will move too many ions across the membrane. the cells will not be able to undergo passive transpor
