Question

The sodium-potassium pump establishes concentration gradients:

(a) Of higher sodium concentrations inside the cell and higher potassium concentrations outside the cell
(b) Of sodium and potassium but the area of their concentrations (inside or outside) depends on the needs of the cell
(c) Of higher potassium concentrations inside the cell and higher sodium concentrations outside the cell
(d) By pumping sodium outside the cell and potassium is cotransported out as well

Answer 1

Particles are moving into and out of the cell, but their concentrations remain stable.

Explanation: i just toke it like no joke just trust

Answer 2

The correct answer is C

Step-by-step explanation:

The sodium-potassium pump is maybe the most well-known pump in biology, and rightly so as it is extremely important for life.

This pump functions by hydrolysis of ATP for energy, and by doing so pumps 3 Na+ molecules to the extracellular space and 2 K+ molecules to the intracellular space. This creates a higher sodium concentration outside the cell and a higher one inside the cell.

This gradient has several functions, such as helping maintain electrochemical neutrality and providing the adequate gradient of cations for signal transduction in neurons, to name a few.
