Passive Transport - an overview

passive transport  Passive transport, most commonly by diffusion, occurs along a high-to-low concentration gradient No energy is necessary for this mode of Passive transport is movement of a substance across a membrane from an area of high concentration to an area of low concentration There is no energy or ATP

Passive transport, most commonly by diffusion, occurs along a high-to-low concentration gradient No energy is necessary for this mode of Active transport is the process by which nutrients, oxygen, water, and other essential molecules are delivered to cells In essence, active and passive

Other than simple and facilitated diffusion, osmosis and filtration are two other techniques that work on the principle of passive transport They are also Contrast · Active transport moves materials from lower to a higher concentration, while passive transport moves materials from higher to lower
