What is A large glucose molecule requires facilitated diffusion but an oxygen molecule referring to?
A large glucose molecule requires facilitated diffusion because it is too big to pass through the cell membrane without assistance from transport proteins. In contrast, an oxygen molecule is small enough to diffuse freely across the cell membrane through simple diffusion due to its size and hydrophobic nature.

What is Facilitated diffusion requires .?
Facilitated diffusion requires the presence of specific carrier proteins or channel proteins embedded in the cell membrane to assist in the movement of molecules across the membrane. These proteins help facilitate the movement of molecules down their concentration gradient, without the need for energy input from the cell. This process is selective and allows only certain molecules to pass through based on their size, shape, and charge.
Three ways that substances can move into and out of a cell?
Substances can move into and out of a cell through passive diffusion, facilitated diffusion, and active transport. In passive diffusion, molecules move from an area of high concentration to low concentration. Facilitated diffusion involves the use of carrier proteins to help molecules pass through the cell membrane. Active transport requires energy to move molecules against their concentration gradient.
How do substances like co2 and water move in and out of the cell?
By the process of diffusion and osmosis.
What is the difference between simple diffusion and facilitated diffusion?
It doesn't. (answer by RRU member Cyrem)
Does facilitated diffusion require the Cell to use energy?
No, there is no ATP used in facilitated diffusion, because it is a form of passive transport. It only differs from normal diffusion in that it uses transport proteins to move larger or more polar molecules across the membrane of the cell.
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.
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.
Diffusion requires what?
Facilitated diffusion requires membrane proteins
Facilitated diffusion required what?
Facilitated diffusion requires membrane proteins
What requires the use of energy and help of transport proteins to move a molecule across a cell membrane?
Facilitated diffusion
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.
What requires the use of energy and the help of transport proteins to move a molecule across the cell membrane?
Facilitated diffusion
What drives Facilitated diffusion?
Facilitated diffusion is a passive process whereby a molecule is "carried" across a semi-permeable membrane by a channel or protein carrier. Like diffusion, this process requires no energy, however, since passive diffusion can drive movement against a concentration gradient it is not really diffusion.
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 is the difference between facilitated diffusion with the help of a carrier molecule with the help of a transport protein?
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
A molecule such as glucose must use a protein channel to cross through a cell membrane?
This is correct. Glucose, being a large molecule, requires a protein channel called a glucose transporter to facilitate its passage through the cell membrane. Glucose transporters assist in transporting glucose molecules across the hydrophobic lipid bilayer of the cell membrane.
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
