GPT 3.5
Facilitated diffusion is a type of passive transport in which molecules move across the cell membrane with the help of transport proteins. These transport proteins act as channels or carriers that allow specific molecules to pass through the membrane.
During facilitated diffusion, molecules move from an area of higher concentration to an area of lower concentration, following the concentration gradient. The transport proteins are specific to certain molecules, which allows for selective transport of specific substances into the cell.
The movement of molecules across the cell membrane in facilitated diffusion does not require energy input from the cell, as it is driven by the concentration gradient. This process is essential for the uptake of essential nutrients such as glucose and amino acids by the cell.
