No, passive membrane transport processes do not involve movement of substances from areas of low concentration to areas of high concentration. Instead, passive processes such as osmosis and diffusion move substances down their concentration gradient, from areas of high concentration to areas of low concentration without requiring energy input.
False. Energy is not required to move molecules from areas of high concentration to areas of low concentration; this process occurs naturally through diffusion, which is driven by the concentration gradient. However, energy is required for active transport, where molecules are moved against their concentration gradient from low to high concentration.
The movement of molecules from an area of high concentration of that molecule to an area of lower concentration is called simple diffusion.
active transport
it moves from high to low concentration
who even knows!
diffusion. novanet.
it moves materials from areas of high concentration on to areas of low concentration
Diffusion.
it moves materials from areas of high concentration on to areas of low concentration
That is incorrect. Osmosis actually causes water to move from areas of high water concentration to areas of low water concentration, in order to equalize the concentration of solutes across a semipermeable membrane.
