Moves substances from a more dilute solution to a more concentrated solution against a concentrated gradient
Does active transport require energy
Yes-energy released from food in respiration to provide the energy required
Whys active transport required in plants
Allows plant root cells to absorb mineral ions required for growth from a very dilute solution in the soil against a concentration gradient
How is active transport used in the body
Enables sugar molecules used for cell respiration to be absorbed from lower concentrations in the gut to the blood where concentration of sugar is higher
