Biology Cell Transport – FAQ
Cell transport refers to the various mechanisms by which substances move in and out of cells. These processes are essential for maintaining cellular homeostasis and enabling cells to perform their functions effectively.
Passive transport involves the movement of molecules across the cell membrane without the need for energy, moving from an area of higher concentration to one of lower concentration. In contrast, active transport requires energy, usually in the form of ATP, to move substances against their concentration gradient, from lower to higher concentration.
The main types of passive transport include diffusion, osmosis, and facilitated diffusion. Diffusion is the movement of molecules from high to low concentration. Osmosis is the diffusion of water across a semi-permeable membrane. Facilitated diffusion involves transport proteins helping molecules cross the membrane.
Active transport is necessary for cells to maintain their internal environment, absorb essential nutrients, and expel waste products. It allows cells to uptake substances that are in lower concentration outside the cell and remove toxins or excess ions that accumulate inside.
Endocytosis and exocytosis are types of active transport. Endocytosis is the process by which cells engulf external substances, forming a vesicle to bring them inside. Exocytosis, on the other hand, involves vesicles fusing with the cell membrane to release their contents outside the cell. Both mechanisms are vital for material exchange and communication between cells.
