How does ATP relate to membrane transport?a. The movement of a substance down its concentration gradientthrough transport proteins requires the hydrolysis of ATP.b. The higher the concentration of ATP in the cell, the more permeablethe membrane is to water and small, nonpolar molecules.d. A cell uses the energy in ATP to transport substances against theirconcentration gradient.c. Digestion produces a high concentration of ATP outside the cell,and the ATP enters the cell via facilitated diffusion.
