Question:
Give an example of active transports in animal cells
Author: Alana RayAnswer:
In animal cells active transport is used to carry the sugar glucose into the cell of the cavity in the small intestine, the lumen. This is where food is digested and molecules such as the digested sugar glucose are produced. Active transport is use to carry glucose because the concentration of sugars in the lumen is lower than the concentration of sugars outside the cell therefore they are unable to diffuse into the cell. Lumen also contains many mitochondria which perform respiration, providing the energy needed for active transport
