WebApr 9, 2024 · Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP). If a substance must move into the cell against its concentration gradient—that is, if the concentration of the substance inside the cell is greater than its concentration in the extracellular fluid (and vice versa)—the cell must use energy … WebEndocytosis ( endo = internal, cytosis = transport mechanism) is a general term for the various types of active transport that move particles into a cell by enclosing them in a vesicle made out of plasma membrane. There are variations of endocytosis, but all follow the same basic process.

WebFeb 5, 2024 · Exocytosis is the process of moving materials from within a cell to the exterior of the cell. This process requires energy and is therefore a type of active transport. Exocytosis is an important process of plant … WebActive transport is the movement of substances from an area of low concentration to a higher concentration , either into or out of cells. During active transport, carriers in the cell membrane ‘pick up’ particles and move them against the concentration gradient. As the name suggests, active transport requires energy from the cell, which is ...
WebActive transport describes the use of energy to move molecules across a cell membrane, usually against their concentration gradients.
