Final answer:
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.
