Active vs Passive Transport
Passive Transport: Passive transport does not require energy and relies on the concentration gradient to move substances. This includes processes like simple diffusion, facilitated diffusion, and osmosis. The movement is always from an area of higher to lower concentration until equilibrium is reached.
Active Transport: Active transport requires energy to move substances against their concentration gradient, from an area of lower to higher concentration. This energy is usually supplied by ATP. Active transport includes processes such as protein-mediated active transport and bulk transport mechanisms like endocytosis and exocytosis.
