Respuesta :
Facilitated diffusion and active transport are two important processes that allow substances to move through a cell membrane. Facilitated diffusion is the movement of substances across a membrane with the help of specific proteins, while active transport is the movement of substances across a membrane requiring energy.
Both processes are essential for cells to take in and expel different substances. An example of facilitated diffusion is the movement of glucose molecules through the cell membrane with the help of a glucose transporter protein. The protein acts as a bridge between the glucose molecules and the cell membrane, allowing them to pass through.
An example of active transport is the movement of sodium and potassium ions across the cell membrane via the sodium-potassium pump. This process requires energy in the form of ATP to pump the ions across the membrane against the concentration gradient.
Describing facilitated diffusion, we can say that it is a passive process that does not require energy, and it involves the movement of molecules across a membrane with the help of proteins. Describing active transport, we can say that it is an active process that requires energy, and it involves the pumping of molecules across a membrane against the concentration gradient.
