How are diffusion and facilitated diffusion diffrent?
Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the membrane.
Can diffusion occur through a nonliving membrane?
Yes, it can.
What the diffusion of water across a cell's membrane?
The diffusion of water through a cell membrane is called osmosis.
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
What are the factors needed for maintaining the direction of diffusion?
Maintaining the direction of diffusion relies on factors such as a concentration gradient (difference in concentration between two areas), permeability of the membrane through which substances are diffusing, and the presence of barriers or channels that guide the diffusion process in a specific direction. Additionally, factors such as temperature, pressure, and size of molecules can also influence the direction of diffusion.

What factors affect the diffusion of water?
One of the factors that affect the diffusion of water through a membrane by osmosis is the permeability of the membrane. The amount of water on each side of the membrane may also have an effect on water's diffusion. Water will diffuse to the side with little water to even out the concentration.
Which affects the rate of diffusion through a semipermeable membrane steeper concentration of gradients higher temperatures or the size of the molecule diffusing?
Steep concentration gradients and higher temperatures both increase the rate of diffusion through a semipermeable membrane. The size of the molecule diffusing also plays a role, as smaller molecules generally diffuse more quickly than larger ones due to their ability to move through the membrane more easily.
What is faciillitated diffusion?
Facilitated diffusion is diffusion that occurs not through the cell membrane directly but through protein channels within the cell membrane. They are often, although not always, substrate specific.
The rate of diffusion through a semipermeable membrane will be lowest when?
The rate of diffusion through a semipermeable membrane will be lowest when temperatures are low. Lower temperatures decrease the energy of the molecules, which in turn decreases the rate of diffusion.
