Active transport moves substances from a region of low concentration to a region of high concentration. Step 5: Speed of Process- Passive transport is generally a slower process compared to active transport, which is typically faster due to the energy input facilitating the movement of molecules. ...
Active Transport Definition Active transport is a kind of cellular transport where substances move against a concentration gradient. This means that the direction is from an area of lower concentration to an area of higher concentration. Hence, this process will require the expenditure of energy, and...

To move substances against a concentration or electrochemical gradient, the cell must use energy. This energy is harvested from ATP generated through the cell’s metabolism. Active transport mechanisms, collectively calledpumps, work against electrochemical gradients. Small substances constantly pass through...

from an area of low concentration to an area of high concentration. The cell uses ATP (adenosine triphosphate) as its energy source to move substances in and out of the cell membranes. Passive transport, on the other hand, is the movement of molecules from higher to lower concentration. ...
