Answer this simple question above on active transport

Active transport is a form of specialized transport that enables cells of living organisms to take in essential nutrients, ions and other fundamental polar molecules for which they are found in high concentrations, but is still required for the organism. It is movement of these substances against the natural diffusion process which is from high to low concentration, active transport is from low to high concentration. Thus it involves energy in various forms to drive this process, usually it comes from the degradation or break down of a phosphate group from a molecule of ATP. This mode of transport also utilizes specific transport proteins to aid in the movement across the selectively permeable membrane of the cells for that organism.
