Question

Na / K ATPase (sodium potassum adenosine triphosphatase) is found in the plasma membrane and catalyzes the exchange of sodium and potassium ions across the membrane. Classify the statements about the transport system as either true or false.

Answer 1

The question is incomplete. The complete question has been attached below.

Answer:

True Statements :

1) Pumps K+ ions into the cell.

2)Pumps Na+ ions out of the cell.

3)Exchange 3 Na+ ions for 2 K+ ions.

4)Creates a membrane potentials that is negative on the inside.

False statements:

1)Pumps Na+ ions into the cell.

2)Pumps K+ out of the cell.

3)Exchange 2 Na+ ions for 3 K+ ions.

4) Transport protein become adenylated by ATP during the transport cycle.

The Na / K ATPase uses energy molecules and shows the active transport. The potassium ions maintain the resting membrane potential of -70 mV and entry of sodium ions depolarize the cell and change the membrane potential around + 30mV. The two potassium ions will move out of cell and three potassium ions will move inside the cell.
