Both of these processes do not require any extra energy or input hence these are called passive processes. Both of these processes observe the movement of molecules from higher concentration areas to lower concentration areas.
WebApr 9, 2024 · Cellular membranes are essential to the survival of all living organisms, as they create a physical boundary between the cell and its environment. These membranes permit the selective passage of certain molecules into and out of the cell, while blocking others. This selective passage occurs through various mechanisms, including diffusion, … WebA diffusion gradient is a gradient in the rates of diffusion of multiple groups of molecules through a medium or substrate. The groups of molecules may constitute multiple …
