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.
Why the line-with-gaps model is not suitable to explain facilitated diffusion?
Facilitated diffusion is a carrier-mediated form of transport across a membrane. The line-with-gaps model doesn't show the carrier proteins that are in the cell membrane. These proteins are what help facilitated diffusion occur.
What term describes the difference between the numbers of hydrogen ions on opposite sides of the membrane?
Diffusion and it does not have to be through a semi permeable membrane.
What three methods allow exchange of molecules between cells and their surroundings?
The three methods are diffusion, facilitated diffusion, and active transport. Diffusion involves the movement of particles from an area of higher concentration to an area of lower concentration. Facilitated diffusion requires the assistance of transport proteins to move molecules across the cell membrane. Active transport uses energy to move molecules against their concentration gradient.
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.
What is the difference between diffusion and facilitate diffusion?
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
What is the difference between facilitated diffusion and simple diffusion in terms of the mechanisms by which molecules move across a cell membrane?
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of specific proteins, while simple diffusion does not require any proteins and relies on the molecules moving freely through the membrane.
What is the difference between diffusion and facilitated diffusion in terms of the movement of molecules across a cell membrane?
Diffusion is the movement of molecules across a cell membrane from an area of high concentration to low concentration without the need for a protein. Facilitated diffusion also moves molecules from high to low concentration, but requires a specific protein to help them pass through the membrane.
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.
What is the difference between passive diffusion and facilitated diffusion?
Passive diffusion is the movement of molecules across a cell membrane from an area of high concentration to low concentration without the need for a protein carrier. Facilitated diffusion, on the other hand, requires the presence of specific protein channels or carriers to help molecules move across the membrane.
What are the differences between diffusion facilitated diffusion and osmosis?
Diffusion is the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion involves the use of transport proteins to move specific molecules across the cell membrane. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
What is the difference between simple diffusion and facilitated diffusion?
It doesn't. (answer by RRU member Cyrem)

What are the similarities between facilitated diffusion and active transport in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion and active transport are both methods of transporting molecules across the cell membrane. They both involve the use of specific carrier proteins to facilitate the movement of molecules. However, the key difference is that facilitated diffusion does not require energy input from the cell, while active transport does require energy in the form of ATP to move molecules against their concentration gradient.
How is active transport similar to facilitated diffusion in terms of their mechanisms of moving substances across the cell membrane?
Active transport and facilitated diffusion are both mechanisms used by cells to move substances across the cell membrane. Both processes require the use of specific proteins embedded in the cell membrane to facilitate the movement of substances. However, the key difference between the two is that active transport requires energy input from the cell to move substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances down their concentration gradient.
What is one similarity shared by osmosis and facilitated diffusion?
One similarity between osmosis and facilitated diffusion is that both involve the movement of molecules across a membrane from an area of high concentration to an area of low concentration, driven by a concentration gradient.
What is the major difference between between facilitated diffusion and active transport?
Facilitated diffusion occurs in order to maintain homeostasis within a cell. If there is more of something, such as water, inside a cell than outside the cell, diffusion allows the water to flow out of the cell so that an equal amount of water molecules exists both inside and outside the membrane. This requires little or no energy from the cell itself. Active transport is when the cell takes in or excretes material through the membrane so that the amount of material inside and outside the membrane is different. This requires energy from the cell to occur.
