If you meant to ask something else (e.g., "definition for active transport in torrenting"? That doesn't exist), please clarify your question.
is the energy-dependent movement of molecules or ions across a cell membrane against their concentration gradient (from an area of low concentration to an area of high concentration). definitely maybe torrentdefinition for active transport
Active transport allows nerve cells to fire, kidney cells to filter blood, and gut cells to absorb nutrients (like glucose) even when levels are low. Summary Table for Active Transport If you meant to ask something else (e
| Feature | Active Transport | Passive Transport (for comparison) | | :--- | :--- | :--- | | | Yes (ATP) | No | | Direction of movement | Low → High (against gradient) | High → Low (with gradient) | | Uses carrier proteins | Yes (pumps) | Sometimes (channels/facilitated) | | Example | Sodium-Potassium pump | Oxygen diffusing into blood | Active transport allows nerve cells to fire, kidney
