An example of secondary active transport is shown below, wherein the movement of sodium ions down their electrochemical gradient (from a high concentration outside the cell to a low concentration inside) is used to power the transport of amino acids out of the cell against their concentration gradient. Is osmosis An example of active transport? Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane. The best understood and most exhaustively studied cases of active transport arc those that involve the movements of sodium and potassium ions across the plasma membranes of erythrocyes, nerve cells, and Nitella cells and that result in an ionic concentration gradient across the cell membrane. Movement of Ca 2+ ions out of cardiac muscle cells. Active transport is a sort of cell transport where substances move against a fixation slope. Here are some examples of active transport in animals and humans: Active transport occurs when cells use energy to move molecules against the concentration gradient. Before sharing your knowledge on this site, please read the following pages: 1. In this manner, the recovery phase would result in an additional movement of ions through the membrane and would be more efficient. Counter transporters or antiporters Counter transporters are also known as antiporters. During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. Some examples of pumps for active transport are Na +-K + ATPase, which carries sodium and potassium ions, and H +-K + ATPase, which carries hydrogen and potassium ions. Even among them, active transport can be of 3 types-primary active transport, secondary active transport and bulk active transport. membrane moving from the higher concentration area to the region of There are several types of bulk transport that are divided into two main categories: exocytosis, which is the transport of large molecules out of the cell, and endocytosis, or the transport of large molecules into the cell.
