In the facilitated diffusion the transport protein is needed as well in the active transport.

What is the diffusion of water through the cell membrane is called?
Facilitated Diffusion
Glucose molecules cross the cell membrane by means of?
The answer is that glucose crosses a semi-permiable membrane by the process of facilitated diffusion. It cannot be by osmosis, because osmosis is the moving of only water from a concentration of high to low.
Compare and contrast diffusion and facilitated diffusion?
They both require a trans membrane protein. Facilitated diffusion does not require energy whereas active transport requires energy. Facilitated diffusion takes place when there is a net movement of molecules from a region of high concentration to a region of low concentration whereas active transport takes place when there is a net movement of molecules from a region of low concentration to a region of high concentration.
How is facilitated diffusion different from passive transport?
Mediated Transport has an extra step of binding to a carrier protein, while Passive transport does not bind to a protein. Both of them however, move along the concentration gradient (High--> Low)
A type of transport in which water moves across a membrane and down its concentration gradient is?
"Active Transport" is the answer given but if it is the passive movement then no energy is required so isn't it facilitated diffusion?
What is the diffusion of water through the cell membrane is called?
Facilitated Diffusion
Which are types of passive transport?
Diffusion - spreading of molecules in solid, liquid and gas Osmosis - diffusion of water; affected by tonicity Facilitated diffusion - transports of substances are facilitated by carrier proteins
Explain the differences among diffusion facilitated diffusion and osmosis?
osmosis is the movement of water across the plasma or cell membrane
What are the similarities between diffusion and facilitated diffusion?
Diffusion is the main method by wich small molecules move across the cell membrane. while many cellular processes depend on osmosis because cells cannot function properly without adequate water. Facilitated diffusion works through channels and Osmosis only works with water.
Glucose molecules cross the cell membrane by means of?
The answer is that glucose crosses a semi-permiable membrane by the process of facilitated diffusion. It cannot be by osmosis, because osmosis is the moving of only water from a concentration of high to low.

Facilitated diffusion takes place when there is a net movement of molecules from a region of high concentration to a region of low concentration whereas active transport takes place when there is a net movement of molecules from a region of low concentration to a region of high concentration.
How simple diffusion can be distinguished from facilitated diffusion?
simple diffusion transports smaller molecules like oxygen and water while facilitated diffusion transports larger molecules like glucose and requires energy
What is the difference between facilitated diffusion and diffusion?
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
Facilitated diffusion sentence?
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.

What moves products through a cell membrane?
Diffusion, facilitated diffusion, Osmosis and Active Transport. Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!
