What are the molecules that help substances move through the cell membrane during active transport and facilitated diffusion?
In simple diffusion, small noncharged molecules or lipid soluble molecules pass between the phospholipids to enter or leave the cell, moving from areas of high concentration to areas of low concentration (they move down their concentration gradient). Oxygen and carbon dioxide and most lipids enter and leave cells by simple diffusion.

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.
Compare and contrast active transport and facilitated diffusion-?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to move molecules down their concentration gradient. Both processes involve the use of proteins to transport molecules across the cell membrane, but active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
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.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
In what process are carrier proteins important?
Carrier proteins is important in facilitated diffusion. Facilitated diffusion transports molecules from one area of higher concentration on one side of the membrane to an area of lower concentration on the other side .Because the molecules are moving down their concentration gradient , facilitated diffusion is passive transport.
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.

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 are substances and structures transported within the cell?
Substances and structures are transported within the cell through processes such as diffusion, facilitated diffusion, active transport, and vesicular transport. Diffusion involves the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion uses protein channels to help substances across the cell membrane. Active transport requires energy to move molecules against their concentration gradient. Vesicular transport involves the formation of vesicles that transport substances within or out of the cell.
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.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
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.
In what process are carrier proteins important?
Carrier proteins is important in facilitated diffusion. Facilitated diffusion transports molecules from one area of higher concentration on one side of the membrane to an area of lower concentration on the other side .Because the molecules are moving down their concentration gradient , facilitated diffusion is passive transport.
How do substances like co2 and water move in and out of the cell?
By the process of diffusion and osmosis.
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 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.
Cell must expend energy to transport substances using?
Facilitated diffusion.
