It also allows sugar molecules to be absorbed from ________ concentra- tions in the gut into the blood which has a higher sugar concen- tration. Sugar molecules are used for cell r​

Answer 1

Active transport moves substances from a more dilute solution to a more concentrated solution, against the concentration gradient. This requires energy expenditure by the cell.

Active transport allows minerals to be absorbed into plant root hairs from very dilute solutions in the soil. It also enables sugar molecules to be absorbed from lower concentrations in the gut into the blood, which has a higher sugar concentration. Sugar molecules are used for cellular respiration and other metabolic processes in cells.

Answer 2

Active transport moves substances from a more dilute solution to a more diluted solution (against the concentration gradient). This requires energy from the cell. Active transport allows mineral ions to be absorbed into plant root hairs from very dilute solutions in the soil. It also allows sugar molecules to be absorbed from lower concentrations in the gut into the blood, which has a higher sugar concentration. Sugar molecules are used for cell respiration and other cellular processes.
