Question

5. The sodium-potassium pump is an example of

i. simple diffusion.
j. passive transport.
facilitated diffusion.
k. none of the above

Answer 1

K

The Sodium-Potassium Pump. Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient. ... In active transport, as carrier proteins are used to move materials against their concentration gradient, these proteins are known as pumps.

Answer 2

its passive transport

Step-by-step explanation:

The sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na+ and K+ at constant disequilibrium.
