What else can I help you with?
Can small hydrophobic molecules cross the cell membrane?
Yes, small hydrophobic molecules can cross the cell membrane.
Can polar molecules cross the cell membrane?
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
Can small polar molecules cross the cell membrane?
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.
Do hydrophobic molecules cross cell membranes?
Yes, hydrophobic molecules can cross cell membranes because cell membranes are made up of a phospholipid bilayer that is permeable to nonpolar molecules like hydrophobic ones.
The interior of the lipid bilayer of a cell membrane forms a nonpolar zone that?
The nonpolar zone in the lipid bilayer of a cell membrane helps to repel polar molecules, allowing for selective permeability of the membrane. This structure is essential for maintaining cell integrity and regulating the passage of substances in and out of the cell.

Can small polar molecules cross the cell membrane?
Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.
What depends on a molecule that can cross the plasma membrane?
The size, charge, and hydrophobicity of a molecule determine its ability to cross the plasma membrane. Small, nonpolar, and uncharged molecules can typically pass through the membrane via simple diffusion, while larger, charged, or hydrophilic molecules may require transport proteins or channels to facilitate their movement.
Do hydrophobic molecules cross cell membranes?
Yes, hydrophobic molecules can cross cell membranes because cell membranes are made up of a phospholipid bilayer that is permeable to nonpolar molecules like hydrophobic ones.

Why oxygen molecules do not across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
What is a factor that determines whether a molecules can cross a cell membrane?
mass
Which is a factor that determines wheathe a molecule can cross a cell membrane?
A key factor that determines whether a molecule can cross a cell membrane is its size and polarity. Small, nonpolar molecules, such as oxygen and carbon dioxide, can easily pass through the lipid bilayer, while larger or polar molecules often require specific transport proteins to facilitate their movement. Additionally, the concentration gradient and the presence of channels or carriers also influence a molecule's ability to cross the membrane.
Which of the following molecules would be blocked by a cell membrane?
Large molecules such as proteins and nucleic acids are typically blocked by the cell membrane due to their size and complexity. Small, nonpolar molecules like oxygen and carbon dioxide can easily pass through the cell membrane through simple diffusion.
What types of molecules can easily go through your cell membrane are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
Ask us is a factor that determines whether a molecule can cross a cell membrane?
A key factor that determines whether a molecule can cross a cell membrane is its size and polarity. Small, nonpolar molecules, like oxygen and carbon dioxide, can easily diffuse through the lipid bilayer, while larger or polar molecules often require specific transport proteins or channels to facilitate their passage. Additionally, the concentration gradient and the presence of membrane proteins can also influence a molecule's ability to cross the membrane.
