What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
What substances would most likely require a protein to facilitate its diffusion across a cell 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.
Which of the following would likely move through the lipid bilayer of a plasma membrane most rapidly?
Water, or small hydrophobic compounds.
Which molecule is most likely to cause osmosis in the body?
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 molecules diffuse through a selectively permeable 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.
What type of molecule would be likely to diffuse across the phospholipid bilayer of the cell membrane?
an ion
Which structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not.?
A semipermeable membrane is a large glucose molecule that requires facilitated diffusion but an oxygen molecule does not.

A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
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 substances would be moved across the cell membrane by diffusion?
Smaller particles are more likely to move by diffusion. Fat soluble substances are also more likely to move through diffusion also.
Would oxygen particles enter a cell through diffusion more likely than fat particles?

What is the difference of facilitated diffusion with the help of a carrier molecule and active transport with the help of a transport protein?
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!
Can osmosis occur across a room?
Osmosis is a transfer through a membrane, so I doubt it. You're likely thinking of diffusion.

Where are you least likely to find water in the plasma membrane?
inside the lipid bilayer
Osmosis is the diffusion of water through a membrane but most of what is called osmosis in cells is actually due to a what related proccess?
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.
