What is required for the Na+/K+ pump to function? Is this diffusion?

Answer 1

The sodium/potassium pump is a good example of active transport of molecules across a membrane. In this example, active transport is coupled to ATP hydrolysis to obtain enough free energy to transport the ions against their concentration gradient. This ion pump is an example of antiport membrane transport, where the transported molecules are pumped across the membrane in opposite directions (as opposed to synport). The sodium gradient is generated for use by cotransport systems, such as the active transport of glucose from the extracellular environment into the inside of the cell. The non-equilibrium state of the sodium gradient is essentially free energy to be used for the import of molecules against their own concentration gradient.

Answer 2

For the pump to function, ATP is required.

No this is termed as active transport. Unlike diffusion, which is a form of passive transport, active transport requires the expenditure of energy in the form of ATP. Energy is required to move the substrate molecules against a concentration gradient, from a region of lower concentration to a region of higher concentration across a partially permeable membrane.

Answer 3

completely fake. The sodium potassium pump is in the plasma membrane of an axon, and restores the membrane to its unique polarized situation. It purely does this by using forcing the debris for the period of a gradient by using which they does not certainly diffuse, and subsequently expenditures the cellular means.

Answer 4

Since ATP required, it is active transport.

Answer 5

it is a combination of both diffusion and active transport via ion channels.

Answer 6

ATP powered, I think.

Answer 7

i am SO glad i get to forget this stuff!
