What else can I help you with?
State one reason why some molecules can pass through a certain membranebut other molecules can not?
Molecules can pass through a membrane if they are small enough to fit through the pores or channels in the membrane. Larger molecules may not be able to pass through due to their size, charge, or inability to interact with the membrane components.
Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
What allows water molecules to pass through?
Water molecules are able to pass through cell membranes via specialized proteins called aquaporins. Aquaporins facilitate the movement of water across membranes by creating a channel for water molecules to pass through while preventing other molecules from entering. This selective permeability helps to regulate the flow of water in and out of cells.
What can pass through the bilayer with ease?
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.
What molecules do not pass through the cell membrane easily while molecules pass through the membrane?
Molecules that do not pass through the cell membrane easily are typically large, polar, or charged, such as glucose, ions (like Na⁺ and K⁺), and proteins. In contrast, small, nonpolar molecules, such as oxygen and carbon dioxide, can easily diffuse through the lipid bilayer of the membrane. Additionally, water can pass through the membrane via specialized channels called aquaporins, though its small size would otherwise allow some diffusion.
Can charged molecules pass through the membrane?
Yes, charged molecules can pass through the membrane.
What are the three molecules that cannot easily pass through the membrane?
The three molecules that cannot easily pass through the membrane are large molecules, charged molecules, and polar molecules.
Which molecules cannot pass through the membrane?
Large molecules such as proteins and nucleic acids cannot pass through the cell membrane.
Can large polar molecules pass through the plasma membrane?
No, large polar molecules cannot pass through the plasma membrane.
Can polar molecules pass through the phospholipid bilayer?
Yes, polar molecules can pass through the phospholipid bilayer through facilitated diffusion or active transport.
State one reason why some molecules can pass through a certain membranebut other molecules can not?
Molecules can pass through a membrane if they are small enough to fit through the pores or channels in the membrane. Larger molecules may not be able to pass through due to their size, charge, or inability to interact with the membrane components.
Can polar molecules pass through the cell membrane?
Yes, polar molecules can pass through the cell membrane with the help of specific transport proteins.
Can hydrophobic molecules pass through a membrane?
Yes, hydrophobic molecules can pass through a membrane because the lipid bilayer of the membrane is also hydrophobic, allowing them to move through easily.
A form of diffusion in which the molecules pass through a protein instead of between the phospholipids is called?
Glucose molecules are molecules that pass through a protein instead of between the phospholipids. This is because they are to big to diffuse through phospholipids.
What do you need to know about filter in order to predict which molecules can pass through?
To predict which molecules can pass through a filter, you need to know the pore size of the filter. Smaller molecules can pass through filters with larger pore sizes, while larger molecules may be blocked. Additionally, the filter material and its properties, such as charge and hydrophobicity, can also influence which molecules can pass through.
What molcule can pass through a lipid bilayer by simple diffusion with no assistance from proteins?
Carbon.water molecules,glucose molecules can pass through lipid bilayer by simple diffusion
Which molecules difuse through the lipid portion of the plasma membrane?
Only nonpolar (hydrophobic) molecules can pass through the bi-lipid membrane. For example, hormones are nonpolar, and they can pass through the membrane.
