Question

Quizplus · Accepted Answer

All of the answer choices are correct. Active transport moves molecules against the concentration gradient, requires proteins embedded within the cell membrane, and requires energy to move molecules across the cell membrane. Simple diffusion occurs from an area of high concentration to an area of low concentration without any energy or proteins required. Active transport is necessary for the movement of larger molecules, ions, and other substances into and out of cells.
