WebJun 27, 2011 · Facilitated diffusion or passive diffusion is the process that facilitates the uptake of nutrients across the cell membrane without utilizing energy. It uses trans-membrane proteins to transport nutrients into the cell. Since it involves integral proteins that are either carrier or channel protein, it differs from the simple diffusion process. WebWhile it does not require energy (similar to the other types of passive diffusion), facilitated diffusion is dependent on transmembrane integral proteins located on the cell membrane for transportation of substances in or out of the cell down …

WebApr 11, 2024 · With facilitated transport, the movement is passive. That is, you have a protein that certain molecules/ions can pass through, but you aren't doing any pumping or using energy to move molecules. That means that the molecules are free to move in either direction, according to concentration (and electrical) gradients. WebNov 5, 2024 · Thus, in all the above three methods like passive diffusion, facilitated diffusion, and osmosis, there is no energy spent on transport. However, in the next methods, transport across the membrane occurs through the use of energy (ATP). Active transport lani rabah hamlaghkem paroles
