The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.

How simple diffusion can be distinguished from facilitated diffusion?
simple diffusion transports smaller molecules like oxygen and water while facilitated diffusion transports larger molecules like glucose and requires energy
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
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.
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
Facilitated diffusion is the process by which glucose can pass through a cell membrane by combining with special carrier molecules.
Diffusion is defined as a movement of molecules?
Is Diffusion the movement of molecules from a greater to a lesser concentration.
How simple diffusion can be distinguished from facilitated diffusion?
simple diffusion transports smaller molecules like oxygen and water while facilitated diffusion transports larger molecules like glucose and requires energy
What drives diffusion?
Diffusion is the movement of ions and other micro molecules across a barrier or membrane. Diffusion is caused by gradients on either side of the membrane.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What term refers to diffusion of water molecules through a selectively preamble membrane?
Osmosis is the diffusion of water molecules through a semi-permeable membrane to equalise osmotic pressure.
Is diffusion of molecules across the cell membrane the most complex type of active?
No, diffusion of molecules across a cell membrane is a passive process, not active, and arguably the least complex.
How do glucose molecules cross a plasma membrane?
Facilitated Diffusion
What make osmosis and diffusion the same?
Molecules travel across the cell membrane from a higher concentration to a lower concentration during both osmosis and diffusion. Diffusion is when molecules move across the cells' membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
Can diffusion occur without membrane?
Diffusion is the movement of molecules kineticly from an area of high concentration to an area of low concentration until they are evenly distributed. Osmosis is the movement of molecules thru a membrane.
Diffusion of water molecules across a selectively permeable membrane?
it is osmosis
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.
How easy or hard is it for polar molecules to pass through the cell membrane?
Polar molecules are effectively charged molecules. It's hard for them to cross the cell membrane because the membrane is comprised of an uncharged phospholipid bilayer. Charged molecules tend to have specific protein channels that allow them to cross the membrane.
