what are the similarities between facilitated diffusion and simple diffusion?
64814
They both work with the concentration gradient which means they go from a high concentration area to a low concentration area. The differences are simple diffusion just goes though the membrane of a cell while facilitated diffusion uses a protein channel.

['thin - for a short diffusion distance.', 'large area - achieved by being long and thin, flat, or folded.', 'moist - so that substances can be dissolved for diffusion to happen.']

1 Answer. simple diffusion moves molecules down concentration gradient while active transport takes them against concentration gradient. ... Simple diffusion happens directly through the cell membrane, while active transport through carrier proteins.

The main difference between the two is that diffusion can occur in any mixture, even when two solutions aren't separated by a semipermeable membrane, whereas osmosis exclusively occurs across a semipermeable membrane. There are actually three types of passive transport processes.

Simple diffusion is the passive movement of solute from a high concentration to a lower concentration until the concentration of the solute is uniform throughout and reaches equilibrium. ... Simple diffusion and osmosis are both forms of passive transport and require none of the cell's ATP energy.

Facilitated diffusion may or may not require energy from ATP. In simple diffusion, the molecules can pass only in the direction of concentration gradient. In facilitated diffusion, the molecules can pass both in direction and opposite of the concentration gradient.

Simple diffusion and osmosis are in some ways similar. Simple diffusion is the passive movement of solute from a high concentration to a lower concentration until the concentration of the solute is uniform throughout and reaches equilibrium.

One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

Facilitated diffusion is the movement of a molecule from an area of high concentration to an area of lower concentration with the help of a protein channel or carrier. ... Active transport is the movement of molecules from areas of low concentration to areas where the molecule is found in higher concentration.

What is the difference between diffusion and facilitated diffusion? Diffusion is the driving force behind the movement of many substances across the cell membrane. ... Facilitated diffusion is where molecules cannot directly diffuse across the membrane pass through special protein channels.

similarities: the similarities in osmosis and diffusion is that they both equalize the concentration of two solutions into a membrane. they both work together to move water molecules from a area of high concentration to a area of low concentration.

Facilitated diffusion is for polar or charged molecules which are relatively small in size, while diffusion is for small particles which are neither polar nor charged that need to cross the cell membrane. ... This video explains the role of membrane channels in the process of facilitated diffusion.

Explanation: Simple diffusion is the movement of molecules from an area of higher concentration to lower concentration. ... Osmosis is the movement of water from an area of less concentration of dissolved particles to an area of high concentration, thus equalizing the concentrations on each side.

Comparing Facilitated Diffusion and Active Transport. ... This process is called passive transport or facilitated diffusion, and does not require energy. The solute can move "uphill," from regions of lower to higher concentration. This process is called active transport, and requires some form of chemical energy.

What are the difference between them? they both change the concentration level outside and inside the cell. Active transport requires energy and moves low to high concentration. Facilitated diffusion is passive transport moves high to low.no energy.

This highlights a noticeable difference between osmosis and facilitated diffusion. Osmosis involves movement of water molecules across a semi permeable membrane. ... A major difference can be noted that osmosis requires water molecules but facilitated diffusion does not require any water molecules.

The differences between osmosis and diffusion it that diffusion refers to the movement of any chemical from one place to another, whereas osmosis exclusively refers to the movement of water across a membrane. also diffusion is the movement of molecules (solute or particles).
