size and polarity
The molecule that will not pass through the phospholipid bilayer of a membrane is a large and polar molecule.
A molecule that is too large or charged would be unable to diffuse through a cell membrane.
Large or polar molecules, such as proteins or carbohydrates, face difficulty in passing through a cell membrane due to their size or charge.
True. The size of a molecule can impact its ability to cross the membrane. Smaller molecules can pass through the membrane more easily through diffusion, while larger molecules may require specific transport proteins or channels to facilitate their passage.
Molecule A is likely smaller and more hydrophobic, allowing it to pass through the cell membrane easily via simple diffusion. Molecule B may be larger, polar, or charged, requiring a transporter or channel for passage across the cell membrane.

Glycogen has a had time passing through a cell membrane in comparison to water.
The molecule will be transported across the membrane by way of a transport protein or protein channel.
Passing electricity a through a molecule of water
Because it is a small molecule, water can diffuse through the cell membrane.
Diffusion
Through diffusion.

What is the situation? Provided a concentration gradient and a molecule that passes through a membrane, diffusion will happen. Generally small and nonpolar molecules will pass through a membrane down a concentration gradient. That doesn't answer your question but it may be the answer your looking for.
