Which of the following processes can be used to bring nutrients into a cell against a concentration gradient?

Question

Active transport processes require the use of energy to move molecules or ions against their concentration gradient, which means that they move from an area of lower concentration to an area of higher concentration. This is necessary for bringing in nutrients that are present at lower concentrations outside the cell but are required in higher concentrations inside the cell. Facilitated diffusion, on the other hand, moves molecules or ions along their concentration gradient, while passive diffusion does not require any energy and moves molecules or ions along their concentration gradient.
