Passive Diffusion Vs Active Transport - Examples and …

WebOne of the most common examples of passive transport is simple diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low … WebActive transport. During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport. Image credit: OpenStax Biology. emily champion

WebMay 7, 2024 · Osmosis. Osmosis is a specific type of diffusion; it is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. Water moves in or out of a cell until its concentration is the same on both sides of the plasma membrane. Semi-permeable membranes are very thin … WebFacilitated diffusion is a type of passive transport that uses specialized proteins, such as channel proteins and carrier proteins, to help molecules move across a cell membrane.
