What else can I help you with?
A molecule that can diffuse freely through a phospholipid bilayer is probably?
By Passive transport i can onlythink of glucose, but by active transport material like water, carbon dioxide, amino acids, sodium and potasium and of course oxygen! :)
What are the three segments attached to the glycerol in a phospholipid?
A hydrophilic phosphate group and two hydrocarbon chains.
Why can oxygen diffuse access a cell membrane but a protein cannot?
Oxygen molecules are small and non-polar, allowing them to easily pass through the lipid bilayer of a cell membrane via simple diffusion. Proteins, on the other hand, are typically large and polar molecules that cannot readily pass through the hydrophobic core of the lipid bilayer. Instead, proteins rely on specific transport mechanisms like protein channels or carriers to cross the cell membrane.
Why can oxygen diffuse across a membrane?
Oxygen is a small, nonpolar molecule that can easily pass through the lipid bilayer of cell membranes by simple diffusion without the need for a specific transport protein. This allows oxygen to move from areas of high concentration to areas of low concentration, such as from the lungs into the bloodstream.
How is oxygen delivered directly to the patient?
Oxygen is delivered directly to the patient through oxygen therapy devices such as nasal cannulas, oxygen masks, and oxygen tanks. These devices provide a controlled flow of concentrated oxygen for the patient to breathe in, helping to increase the oxygen levels in their blood.
Can CO2 pass through the phospholipid bilayer?
oxygen
What can pass through 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.
What can cross the phospholipid bilayer?
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.
What are 4 small molecules that can move easily through the phospholipid bilayer?
i do not know all four, but i know three are: O2 (Oxygen) CO2 (Cardon Dioxide) and H2O (Water)
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.
What substance can pass through the lipid bilayer i.e. in between the phospholipid molecules?
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.
Which materials will pass through the bilayer?
oxygen and carbon dioxide.
Why can co2 and o2 cross the phospholipid bilayer without help from proteins?
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.
Process where oxygen and carbon dioxide are exchanged through cell membrane?
Gas exchange occurs through the process of diffusion. Oxygen passes from areas of high concentration in the environment to lower concentration in the cell, while carbon dioxide passes from the cell to the environment. This is facilitated by the phospholipid bilayer of the cell membrane.
What creates selective permebility of plasma membrane?
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.

What substance is most likely to passively diffuse across the plasma membrane by dissolving in 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.
