What does semi permeable membrane do?
I semi-permeable membrane is a membrane when only certain substances can pass through it.it is a membrane that will only allow certain molecules through it . in general oxygen , food and water are allowed to enter ; waste products are allowed to exit and harmful substances are kept out. hope this helps.
Why do oxygen molecules easily diffuse across a cell membrane while glucose molecules do not?
Oxygen molecules are small and nonpolar, which allows them to easily pass through the hydrophobic lipid bilayer of the cell membrane via simple diffusion. Glucose molecules, on the other hand, are larger and polar, making it more difficult for them to move through the nonpolar interior of the lipid bilayer. They require specific transport proteins or channels to facilitate their movement across the membrane.
What particle can penetrate cell membrane easily?
particles that are small and hydrophobic and semipermeable. hydrophobic ions those that are soluble in lipids-- can easily pass through the membrane. In addition, small molecules like O2can sneak between the phospholipids of the membrane. On the other hand, hydrophilic molecules (like water and glucose) and ions (such as sodium ions and hydrogen ions) cannot pass directly through the phospholipids of the plasma membrane.
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.
Does the plasma membrane separate the contents of the cell from its environment?
it encloses the cell and separates its contents from the surroundings.
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.
Oxygen diffuses through what structure?
A semipermeable membrane.
Why do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?
Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.
The statement below refers to a structure of the cell oxygen diffuse through this structure but sodium ion may need active transport which structure is this statement most likely referring to?
a semipermeable membrane

How does Oxygen cross cell membrane?
Oxygen and water molecules can penetrate the cell membrane due to small gaps that are created by the lipid molecules. Lipid molecules overlap each other which makes the gaps. The oxygen and water molecules then enter in the gaps. The cell membrane in this case is semi permeable.

How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.
What kind of molecules can easily pass through a cell membrane?
Small, Non-polar molecules. If the molecule is polar, it sticks to both sides of the membrane, and has to go through selective routes. The easiest to get through is the Non-polar (oxygen and carbon).
