Definition: active transport is the process in which energy is used to move particles from a region of lower concentration to a region of higher concentration through a partially permeable membrane. #BiologyDefinitions **Requires energy from respiration
No Oxygen - No respiration - no energy - no active transport. (anaerobic respiration can also be used for active transport btw)
Where does active transport occur Only in living things as living things respire Some energy released during respiration used in active transport
| Human body: Uptake of glucose by the microvilli of epithelial cells in the small intestine, and from kidney tubules into the blood capillaries. | Plants: Root hair cells take in mineral salts from soil solution by diffusion or active transport. (depending on concentration of mineral salts in soil solution) (in the form of ions) |
