GENERAL HISTOLOGY

Detailed explanation-1: -Exocytosis, endocytosis and sodium-potassium pump are a few examples of active transport. The process of endocytosis and exocytosis are utilized by all the cells for transportation of molecules which cannot passively permeate via the membrane.

Detailed explanation-2: -Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell. There are different variations of endocytosis, but all share a common characteristic: the plasma membrane of the cell invaginates, forming a pocket around the target particle.

Detailed explanation-3: -The sodium-potassium pump is the most prevalent and well-known example of active transportation. On the cell membrane, a sodium-potassium pump moves 3 sodium ions outside the cell and 2 potassium ions inside the cell per ATP.

Detailed explanation-4: -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.
