Facilitated diffusion:
- Does not require energy
- Is still passive transport (like normal diffusion)
- Is still diffusion down a concentration gradient.
- Requires the assistance of membrane proteins.
Active Transport:
- Requires energy (ATP).
- Is NOT passive transport.
- Substance is translocated across the membrane AGAINST a gradient.
- Requires use of energy-induced carrier transport proteins.
Comparison:
- Both require transport proteins.
- One requires energy where the other doesn't.
- One is active, one is passive.
- One moves down a concentration gradient where the other moves against.

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.
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
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 are the similarities between active transport and facilitated diffusion in terms of their mechanisms of transporting molecules across the cell membrane?
Both active transport and facilitated diffusion are mechanisms that transport molecules across the cell membrane. They both involve the movement of molecules from an area of higher concentration to an area of lower concentration. However, active transport requires energy input from the cell to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules pass through the membrane.
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 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.
What is the similarity between simple diffusion and facilitated diffusion?
both need transport protein

What is the difference between active transport and passive transport mean?
Passive transport is a form of transport that does not require an input of energy. Examples include diffusion, osmosis and facilitated diffusion. On the other hand, active transport is a form of transport that requires an input of energy in the form of ATP (adenosine triphosphate). This energy is required for processes such as moving molecules against the concentration gradient.
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.

Differences between active transport and facilitated diffusion?
Active transport requires energy in the form of ATP to move molecules against their concentration gradient, while facilitated diffusion uses carrier proteins to move molecules down their concentration gradient without requiring energy. Active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
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.
