Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.
Only active diffusion requires energy.
What else can I help you with?
What does active transport and facilitated diffusion have in common?
Both active transport and facilitated diffusion are methods of moving substances across cell membranes. Active transport requires energy input to move substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances along their concentration gradient with the help of transport proteins.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
What are some characteristics of facilitated diffusion?
Facilitated diffusion is a passive process that involves the movement of molecules across a cell membrane with the help of transport proteins. It does not require energy input. This type of diffusion is selective, meaning that only specific molecules can pass through the membrane with the assistance of transport proteins.
Facilitated diffusion depends on?
Facilitated diffusion depends on the presence of specific transport proteins in the cell membrane that help to transport specific molecules across the membrane. These transport proteins facilitate the movement of molecules down their concentration gradient, without requiring energy input from the cell.
How do facilitaed diffusion and active transport differ?
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of a specific protein carrier, while active transport uses energy in the form of ATP to transport molecules against their concentration gradient. Facilitated diffusion does not require energy input, whereas active transport does.
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Does facilitated diffusion require energy for the transportation of molecules across the cell membrane?
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
Does the facialited diffusion require the cell to use energy?
No, it does not require energy use from the cell.
How is facilitated diffusion diferant froma an active transport?
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
What are the three transport processes that do not require cell energy?
Passive Transport,Facilitated Diffusion, and Simple Diffusion
Which process requires no energy from the cell?
Passive transport. This process allows molecules to move across the cell membrane without the use of energy. It includes simple diffusion, facilitated diffusion, and osmosis.
How is active transport different than simple and facilitated diffusion?
simple and facilitated diffusion don't require energy and are forms of passive transport. Active transport requires energy
What does not require energy from the cell?
I believe it is facilitated diffusionendocytosis
Do cells gain and then use energy through facilitated diffusion?
Cells do not gain energy through facilitated diffusion. Facilitated diffusion is a passive process in which molecules move across the cell membrane from an area of higher concentration to lower concentration with the help of transport proteins, without the need for energy input. Cells use energy through other processes such as active transport and cellular respiration to maintain their functions.
