How Does Active Transport Work In A Cell __link__

Several key players are involved in active transport, including:

| Type | Direct Energy Source | Example | |------|----------------------|---------| | | ATP directly | Sodium-potassium pump, calcium pump | | Secondary active transport | Uses an electrochemical gradient (made by primary transport) | Sodium-glucose cotransporter (SGLT) in gut/kidneys | how does active transport work in a cell

Primary active transport involves the direct use of ATP to transport molecules across the cell membrane. This process is carried out by a group of proteins called pumps, which use the energy from ATP hydrolysis to move molecules against their concentration gradient. The most common example of primary active transport is the sodium-potassium pump (Na+/K+ pump), which is found in the cell membranes of most cells.
