Which particles can diffuse easily througn a cell membrane?
Oxygen
What molecule is able to easily diffuse across the cell's membrane?
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
What substances easily diffuse a class of cell membrane?
sperm
Gases diffuse most efficiently across what?
Diffusion of gases easily occurs across a membrane. The gases will have to be converted into liquids so as to diffuse easily.
What molecules would easily be able to diffuse through a cell membrane without the help of a transport protein?
Water, any small molecule and lipids.
Why can carbon dioxide move easily through a membrane?
Carbon dioxide is a relatively small molecule, and can diffuse through semi-permeable membranes easily, providing that it moves down a higher concentration gradient.
What is the main reason Na and K ions CANNOT easily diffuse through plasma membranes?
they are hydrophilic and can't cross the hydrophobic region of the plasma membrane
What is an example for selectively premeable?
The phospholipid bilayer that composes the cell membrane is an example of a selectively permeable membrane. It only lets through small, non-polar molecules.
What are 2 substances that diffuse freely across a cell membrane?
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
Why cant polar molecules and ions diffuse across the cell membrane?
Ions cannot diffuse through a phospholipid bilayer because they are not able to dissolve in lipids, hence the phosphoLIPID bilayer . Also, since they have an electrical charge, they are repelled by the membrane.
What are you considering when you referring to how easily materials can pass through membrane?
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
What is an example of molecules that diffuses into a cell?
water
