Question
Almost all cells in the body contain Na K ATPase pump in their plasma membranes.it is the example of one of the following Transport mechanismSelect one:a. Uniportb. Antiportc. Co transportd. Symport
Solution
The Na K ATPase pump is an example of an Antiport transport mechanism.
Here's why:
Transport mechanisms across a cell membrane can be classified into several types, including uniport, antiport, co-transport, and symport.
-
Uniport: This mechanism transports a single type of molecule in one direction.
-
Antiport: This mechanism transports two types of molecules in opposite directions.
-
Co-transport (or symport): This mechanism transports two types of molecules in the same direction.
The Na K ATPase pump is a type of protein that pumps sodium ions out of the cell and potassium ions into the cell, each against its concentration gradient. This is done in a ratio of 3 sodium ions out for every 2 potassium ions in. Since it transports two types of ions in opposite directions, it is an example of an Antiport transport mechanism.
So, the correct answer is b. Antiport.

The sodium-potassium (Na+/K+) pump functions like an antiporter transporting Na+ and K+ icons across membranes using ATP. This protein spans the membrane with intracellular and extracellular domains. It has a binding site for Na+, K+, and ATP. An experiment was conducted to determine the locations of these binding sites. Artificial cells were created and incubated in buffers containing ATP, ouabain (or g-strophanthin, a cardiac glycoside), Na+, and K+ in varying combinations inside and outside of the cells, as indicated in the given table. The transport of Na+ and K+ was measured to determine the activity of the Na+/K+ pump.Which conclusion is supported by the data?A. The ATP binding site of the Na+/K+ pump is located on the intracellular domain of the pump.B. Ouabain does not disrupt ATP binding to the Na+/K+ pump.C. ATP is required for the transport of Na+ and not for transport of K+.D. The ATP binding site of the Na+/K+ pump is located on the extracellular domain of the pump.
