What particles can diffuse directly through the lipid bi-layer?
As the bilayer contains hydrophobic fatty acid tails, water-soluble molecules cannot diffuse directly through. However, lipid soluble molecules such as oxygen can diffuse directly through. Overall, for a molecule to be able to diffuse directly through it must be lipid-soluble, relatively small and non-polar.
Two molecules that move across membrane using simple diffusion?
Oxygen and nitrogen can as they are lipid soluble, as well as water molecules due to their small size.
Which substances readily diffuse through the membrane?
Small and non-polar molecules can readily pass through the cell membrane. They follow the concentration gradient, moving from the higher concentration area to the region of lower concentration.
Why can molecules that are fat-soluble permeate across a cell membrane?
Cell membranes are composed of a lipid bilayer. Cellular fluid (cytosol) and the cell's organelles are contained by the cell's membrane, which is composed of a lipid bilayer. Lipids are a type of fat. Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol.
Is the allergen in poison Ivy sap a water-soluble or lipid- soluble molecule. explain your reasoning?
Lipid-soluble because water spreads poison ivy

Why does NaCl not require a transport protein for diffusion?
It does require a transport protein as it disassociates into charged ions and it is not lipid soluble. Only lipid soluble molecules diffuse freely through living membranes.
Why do mole drug molecules have both water-soluble and oil-soluble functional groups?
The drug has to be water soluble to dissolve as gastrointestinal fluid is aqueous. The drug also has to be oil soluble as only the lipid soluble non-ionized form can readily diffuse across the lipid membrane.
What substance is most likely to passively diffuse across the plasma membrane by dissolving in the membrane?
Lipid-soluble molecules such as O2 and CO2 diffuse freely through the plasma membrane.
Two molecules that move across membrane using simple diffusion?
Oxygen and nitrogen can as they are lipid soluble, as well as water molecules due to their small size.
How do Lipid-soluble molecules and gases enter the cell?
diffusion through the lipid bilayer.
What influence cell diffusion?
Several factors influence cell diffusion. For example, the polarity of the molecule to be diffused and the size of the molecule. Both of these factors may determine whether or not diffusion will be passive or facilitated. The lipid bi-layer of the cell membrane favors lipid soluble molecules and will allow quick passive diffusion of these molecules. Water soluble molecules may need to diffuse through protein channels, lipid rafts phagocytosis or facilitated diffusion. Check Wikipedia for definitions of these processes.
Nonpolar molecule that is not soluble in water?
Lipid are nonpolar molecules that is not soluble in water.
Is growth hormone water soluble or lipid soluble?
lipid soluble
Why will water-soluble molecules have a hard time moving through the lipid bilayer of a cell?
false
Why non polar molecules diffuse more rapidly through membranes than polar molecules?
The implication of non-polar molecules diffusing more rapidly than polar molecules to the transport of substances through the plasma membrane is quite significant. Concentrate gradients are established which facilitate the transport of vital molecules.
Why can only molecules that are fat soluable permate a cell membrane?
The cell wall itself is made of lipid. To be more precise, the cell membrane is made of a bilayer of phospholipids. The hydrophobic fatty acid tails prevent water-soluble molecules passing through, but allow the transport of lipid-soluble molecules.
