Occurs when water molecules diffuse through a membrane?
Osmosis. This is the movement of water molecules from an area of high water concentration to an area of low water concentration across a semi-permeable membrane.
What facilitates the diffusion of water across the cell membrane?
Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable. Simple diffusion and facilitated diffusionare similar in that both involve.
Does sugar diffuse through the cell membrane?
No. Only non-polar, small molecules can pass through a membrane by simple diffusion. A sucrose molecule is too large a molecule to pass through a membrane by simple diffusion, however, it can pass through a plasma membrane (but not any artificial membranes like Visking tubings) by facilitated diffusion, i.e. through transport proteins(specific carriers for sucrose) embedded in the membranes. ! =)
Why does osmosis cross the membrane?
Osmosis occurs across a membrane due to the movement of solvent molecules (usually water) from an area of lower solute concentration to an area of higher solute concentration to equalize the concentration on both sides of the membrane. This process is driven by the tendency of solutes to diffuse and reach equilibrium.
Is water always able to diffuse through a cells selective permeable membrane?
Yes, due to its very small molecular size - unless of course it is frozen.

Osmosis. This is the movement of water molecules from an area of high water concentration to an area of low water concentration across a semi-permeable membrane.
The layers through which the respiratory gases diffuse are known as the?
The layers through which respiratory gases diffuse are known as the respiratory membrane. This membrane consists of the alveolar epithelium, basement membrane, and capillary endothelium. The exchange of oxygen and carbon dioxide occurs through this membrane during respiration.
What part of the lung do oxygen molecules diffuse across into the bloodstream?
Oxygen molecules diffuse across the alveolar membrane in the lungs into the bloodstream. This is where gas exchange occurs, with oxygen moving from the alveoli into capillaries surrounding the alveoli.
What facilitates the diffusion of water across the cell membrane?
Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable. Simple diffusion and facilitated diffusionare similar in that both involve.
Gases diffuse most efficiently across what?
Gases diffuse most efficiently across a thin membrane or barrier. This is because a thin membrane allows for quicker movement of gas molecules from an area of high concentration to an area of low concentration.
Does sugar diffuse through the cell membrane?
No. Only non-polar, small molecules can pass through a membrane by simple diffusion. A sucrose molecule is too large a molecule to pass through a membrane by simple diffusion, however, it can pass through a plasma membrane (but not any artificial membranes like Visking tubings) by facilitated diffusion, i.e. through transport proteins(specific carriers for sucrose) embedded in the membranes. ! =)
Which term refers to the diffusion of water molecules through a slestively permaeable membrane?
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 does diffusion occur through a semipermeable membrane?
Diffusion through a semipermeable membrane occurs when molecules move from an area of high concentration to an area of low concentration, passing through the membrane. This process is driven by the natural tendency of molecules to spread out and reach equilibrium. The semipermeable membrane allows only certain molecules to pass through based on their size and charge, regulating the movement of substances across the membrane.

How would you define cellular diffusion?
Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.
