Can Cells Drive Molecules Across Their Membranes? The Science of Active and Passive Transport - postfix

Active transport involves the movement of molecules against their concentration gradient, requiring energy input. This process is essential for maintaining cellular homeostasis, as it enables cells to take in necessary nutrients and eliminate waste products. Active transport is often mediated by specialized proteins, which use energy from ATP to facilitate the movement of molecules across the cell membrane.

Passive transport, on the other hand, involves the movement of molecules along their concentration gradient, from an area of higher concentration to an area of lower concentration. This process is driven by diffusion, the random movement of molecules. Passive transport is crucial for maintaining cellular balance and is often facilitated by the cell membrane's semipermeable nature.
