Final answer:
The process in which a molecule is moved from an area of low concentration to an area of high concentration is known as active transport and it requires energy, typically ATP.
Step-by-step explanation:
When a molecule is moved from an area of low concentration to an area of high concentration, active transport is occurring. Unlike passive diffusion and osmosis, which move substances down the concentration gradient, active transport requires energy to move substances against the gradient. Proteins in the cell membrane act as pumps, utilizing cellular energy in the form of ATP to carry out this process.
