Question

The concentration of potassium is high and replenished in this area. The higher concentration is maintained by the process of:

A) Active transport
B) Passive diffusion
C) Osmosis
D) Facilitated diffusion

Answer 1

The maintenance of high potassium concentration in this area is maintained by active transport.

Step-by-step explanation:

The maintenance of high potassium concentration in this area is maintained by

active transport

.

Active transport is a process that uses cellular energy (ATP) to move substances against their concentration gradients. In this case, the sodium-potassium pump is an example of an active transport pump that moves three sodium ions out of the cell and two potassium ions into the cell, maintaining a higher concentration of potassium inside.
