Phagocytosis is also important in animals' immune responses as it is the primary way white blood cells destroy invasive organisms like bacteria. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane. But opting out of some of these cookies may affect your browsing experience. As these transport processes require energy, they are known as active transport processes. Active transport requires some form of energy to push the molecules against their gradient; the most common source of this energy is ATP (adenosine triphosphate). 4 Is osmosis An example of active transport? When you learn more about biological processes, you learn more about life. Active transportation is a system of cell transportation that allows cells to move through the membrane of a specific area with less concentration to another high concentration. This causes less ATP to be produced and therefore, less ATP is available for the active transport needed in mineral uptake. There are two main types of active transport: Primary (direct) active transport - Involves the direct use of metabolic energy (e.g. Learn what active transport is and how it takes place. This requires the expenditure of energy on the part of the cell and is called active transport. from low concentration to high concentration.
