What does facilitated diffusion across a biological membrane require?
Facilitated diffusion across a biological membrane requires specific carrier proteins or channel proteins to help transport molecules across the membrane. These proteins facilitate the movement of molecules down their concentration gradient, from an area of high concentration to an area of low concentration, without the need for energy input.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
In what ways are active transport and facilitated diffusion similar?
Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.
What movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
Facilitated diffusion required what?
Facilitated diffusion requires membrane proteins
Diffusion requires what?
Facilitated diffusion requires membrane proteins
What does facilitated diffusion across a biological membrane require?
Facilitated diffusion across a biological membrane requires specific carrier proteins or channel proteins to help transport molecules across the membrane. These proteins facilitate the movement of molecules down their concentration gradient, from an area of high concentration to an area of low concentration, without the need for energy input.
Does osmosis or facilitated diffusion require the presence of membrane channels?
Facilitated diffusion requires the presence of membrane channels or transporters to move molecules across the membrane. Osmosis, on the other hand, does not require membrane channels as it involves the passive movement of water molecules through the lipid bilayer of the membrane.
What form of passive transport always requires membrane-bound proteins?
Facilitated diffusion
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What does facilitated diffusion requires?
Facilitated diffusion requires the presence of specific carrier proteins embedded in the cell membrane to help transport molecules across the membrane. These carrier proteins assist in the movement of molecules down their concentration gradient without requiring energy input from the cell.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
What is falicitated diffusion?
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
Which structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not.?
A semipermeable membrane is a large glucose molecule that requires facilitated diffusion but an oxygen molecule does not.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
