Quizplus · Accepted Answer

Transport of molecules against the concentration gradient requires the use of energy in the form of ATP and a transport protein to facilitate the movement of molecules across the membrane. Option A is incorrect because only ATP is used, not ADP. Option C is incorrect because osmosis and diffusion only apply to movement of molecules down the concentration gradient. Option D is incorrect because ADP is not used in this process.
