sodium potassium pump

Na+ K+

Thus, ________ ATPase is an enzyme within the pump protein that hydrolyzes ATP to get the energy to operate the pump.

Na+

________ needs to be 10- 20 higher on the outside of the cell as compared to the inside.

Amino acids

________, some sugars, and ions are transported by solute pumps.

Symport

________: both moved in the same direction.

ATP

________ energizes protein carriers, and in most cases, moves substances against concentration gradients.

Antiport

________: moved in opposite directions.

Na+

________ will leak back into the cell by facilitated diffusion, other substances (amino acids, glucose, ions) get dragged along with it.

Na+

________ and K+ are necessary for water balance of all cells.

coupled systems

more than one substance

symport

both moved in the same direction

antiport

moved in opposite directions

primary active transport

where energy is provided by the hydrolysis of ATP

secondary active transport/co-transport

which is driven indirectly by passive ion gradient created by the operation of the primary transport

primary active transport

Na+-K+ pump

secondary active transport

co-transport
