Try a nonpolar lipid!
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
Quick answer: glucose Explanation: Any substance that the membrane selects against requires integral proteins to cross the membrane. B/c the lipid bilayer is selectively permeable, not all substances can pass through it by diffusion or osmosis. However, when the cell requires a substance that it's membrane does not easily allow to pass through, it must enter via the proteins in the membrane. They can either be carrier proteins or protein channels depending on the substance. One example of a substance which requires facilitated diffusion is glucose.
Water, or small hydrophobic compounds.
The small molecules like those of water will most likely cause osmosis n the body. This will happen when water flow through the membrane.
Water diffuses by facilitated diffusion, passing through water permeable protein channels embedded in the cell membrane. Water molecules can not pass through the lipid bilayer because water is polar. However, polar molecules pass though the cell membrane through the protein channels. The proteins that aid water in passing through the cell membrane are called aquaporins. "Aqua" for water, and "porin" for pore. A "water pore" in essence.

A semipermeable membrane is a large glucose molecule that requires facilitated diffusion but an oxygen molecule does not.

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.
Small, non-polar molecules like oxygen and carbon dioxide are likely to move via passive transport through a phospholipid bilayer. These molecules can easily diffuse across the lipid bilayer due to their size and hydrophobic nature. Larger or polar molecules generally require other mechanisms such as facilitated diffusion or active transport to cross the membrane.
Nonpolar molecules like lipid-soluble substances (e.g., steroid hormones, oxygen, and carbon dioxide) are most likely to passively diffuse across the plasma membrane by dissolving in the lipid bilayer. This type of diffusion does not require a specific transport protein and can occur directly through the phospholipid bilayer due to the molecules' hydrophobic nature.

The carrier mole accompanies the transported mole through the plastic brain, and is then sent across the bran.sport teens channels are most likely very large and are as such bedded in the bi layer!

Diffusion and Convection. In molecular diffusion, the moving entities are small molecules. Diffusion is the thermal motion molecules at heated temperature. Diffusion rate is a function of only temperature, and is not affected by concentration. I do believe this answer is most likely wrong.
