What kind of molecules can easily pass through a cell membrane?

Small, Non-polar molecules. If the molecule is polar, it sticks to both sides of the membrane, and has to go through selective routes. The easiest to get through is the Non-polar (oxygen and carbon).

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.
What kinds of molecules pass through a cell membrane most easily?
small and hyrdophobic molecules
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
Describe how the diffusion of ions across a cell membrane differs from the diffusion of nonpolar molecules across the cell membrane?
Ions need to be facilitated through a cell membrane because they are passing through a phospholipid bilayer with a hydrophobic interior. Non polar molecules are also hydrophobic, so they can pass through the membrane easily if they are small enough. Ions are polar, so they have a hard time passing through membranes.
Molecules A and B are both organic molecules found in many cells when tested it is found that molecule A cannot pass through a cell membrane but molecule B easily passes through state one way the two?
The molecules differ in size. B must be smaller than A because it can diffuse through the semipermeable cell membrane.

When do molecules not get through the cell membrane?
when your not breathing
What part of the cell membrane allows small molecules to pass through?
the cell membrane
Why is it necessary that you digest hydrolyze starchy food?
Sugar molecules are more easily transported through the cell membrane than larger starch molecules.
Which molecues cross the membrane of a cell easily and which do not?
Non-polar molecules (such as fatty acids, steroid hormones and O2) pass freely through the cell membrane. Small uncharged molecules (such as H2O) also pass freely, but are slower. Large, polar molecules and ions (such as Na+ and K+) do not pass freely. Macromolecules (such as proteins and polysaccharides) do not pass through the cell membrane. Molecules and ions that cannot pass freely through the cell membrane rely on other means, such as protein transporters, to move in to the cell.
