Active transport Flashcards
What is active transport?
The movement of substances from a low to high concentration across a partially permeable membrane using energy from respiration and transport protein.
What is the word equation for respiration?
Glucose + oxygen = ATP (energy) + CO2 + water
Suggest how the highly folded cell surfaces helps the epithelial cell to absorb soluble food?
The folded surface provides a large surface area for more and faster absorbtion/
Name one food molecule absorbed into the epithelial cells by active transport.
glucose.
Suggest why epithelial cells have many mirochondria.
More mitochondria means more respiration and this means more energy for active transport.
Name two substances transported by the xylem in plants?
Water and ions.
describe the process of active transport in the root hair cells of plants.
Take up substances/ions against the conc gradient thought the partially permeable membrane by the energy from the mitochondria through the transport protein.
