Detailed explanation-1: -The sodium-potassium pump is an example of active transport because energy is required to move the sodium and potassium ions against the concentration gradient.

Detailed explanation-2: -The sodium-potassium pump carries out a form of active transport-that is, its pumping of ions against their gradients requires the addition of energy from an outside source. That source is adenosine triphosphate (ATP), the principal energy-carrying molecule of the cell.

Detailed explanation-3: -Examples of Active Transport Phagocytosis of bacteria by Macrophages. Movement of Ca2+ ions out of cardiac muscle cells. Transportation of amino acids across the intestinal lining in the human gut. Secretion of proteins like enzymes, peptide hormones, and antibodies from different cells.

Detailed explanation-4: -The sodium-potassium pump (Figure below) is an example of an active transport pump. The sodium-potassium pump uses ATP to move three sodium (Na+) ions and two potassium (K+) ions to where they are already highly concentrated. Sodium ions move out of the cell, and potassium ions move into the cell.

Detailed explanation-5: -The Na+ K+ pump is an electrogenic transmembrane ATPase first discovered in 1957 and situated in the outer plasma membrane of the cells; on the cytosolic side. [1][2] The Na+ K+ ATPase pumps 3 Na+ out of the cell and 2K+ that into the cell, for every single ATP consumed.
