i do not know all four, but i know three are:
O2 (Oxygen)
CO2 (Cardon Dioxide)
and H2O (Water)
Molecules that are not polar or ion molecules. That is because they won't be stopped by the hydrophobic tails and they will have the acknowledgement to pass through the cell membrane thanks to little resistance. This makes those molecules have an advantage.
Water-soluble molecules generally cannot easily pass through the phospholipid bilayer due to its hydrophobic core, which repels polar substances. Instead, these molecules typically require specific transport proteins, such as channels or carriers, to facilitate their entry into cells. This selective permeability allows cells to control their internal environment effectively.
Non-polar molecules, small polar molecules, and gases like oxygen and carbon dioxide can pass through the lipid bilayer passively due to its semi-permeable nature. These molecules can easily diffuse through the hydrophobic core of the membrane.
The diffusion of small nonpolar molecules through the phospholipid bilayer is known as simple diffusion. This process occurs as these molecules, such as oxygen and carbon dioxide, pass directly through the lipid bilayer without the need for transport proteins. Due to their small size and nonpolar nature, they can easily navigate through the hydrophobic core of the membrane, moving from areas of higher concentration to areas of lower concentration. This passive transport does not require energy input from the cell.
It is because of the make up of the membrane. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Other do pass through easily. A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.
Small, non-polar molecules like oxygen and carbon dioxide can pass through the phospholipid bilayer easily. Larger or charged molecules may need special transport proteins to help them cross.
Small, non-polar molecules like oxygen and carbon dioxide can easily cross the phospholipid bilayer of a cell membrane. Larger or charged molecules typically need the help of transport proteins to pass through.
Yes, oxygen molecules are small and nonpolar, allowing them to pass directly through the phospholipid bilayer of cells by simple diffusion. This is one of the reasons why oxygen can easily enter and exit cells to support cellular respiration.

Yes, nonpolar molecules can cross the lipid bilayer because the lipid bilayer is made up of nonpolar molecules itself, allowing nonpolar molecules to pass through easily.
Carbon dioxide (CO2) and oxygen (O2) are small, non-polar molecules that can diffuse across the phospholipid bilayer due to their size and hydrophobic nature. This allows them to pass through the lipid core of the membrane without the need for specific transport proteins.
Small, nonpolar molecules like oxygen and carbon dioxide pass through a lipid bilayer most easily due to their ability to dissolve in the hydrophobic interior of the membrane. These molecules do not require the assistance of transport proteins to cross the lipid bilayer.
The lipid bilayer of the cell membrane repels water due to its hydrophobic nature. The hydrophobic tails of the phospholipids face inward and prevent water molecules from passing through easily, creating a barrier. This property helps regulate the movement of molecules into and out of the cell.
No, not all substances can pass freely through the phospholipid bilayer of a cell membrane. Small, non-polar molecules like oxygen and carbon dioxide can diffuse across easily, while larger molecules and charged ions require specialized transport mechanisms such as channels or carriers to move in and out of cells.
