Naturally, molecules move from an area of high concentration to low concentration without the need of energy. This type of movement is passive transport. Molecules with strong electrical charges such as ions cannot simply diffuse across the cell membrane. Irrespective of their size, their charge prevents them from moving freely across the cell membrane.
Best Answer: There are two ways that the molecules move through the membrane: passive transport and active transport. Active transport requires that the cell use energy that it has obtained from food to move the molecules (or larger particles) through the cell membrane.Passive transport does not require such an energy expenditure, and occurs spontaneously. The principle means of passive transport is diffusion.ctive transport requires that the cell use energy that it has obtained from food to move the molecules (or larger particles) through the cell membrane.
