Question: The process is active transport. Active transport is a process in which the cell uses energy in the form of ATP to move substances across the plasma membrane against their concentration gradient (from an area of lower concentration to a higher concentration). In this case, potassium ions are moved into the cell even though their concentration is already much higher inside. This allows the cell to maintain a concentration of potassium ions that is much greater than in the surrounding environment. Please add one more sentence little tiny bit in it. Need Assignment Help?
