Which is a factor that determines wether a molecule can cross the cell membrane?
Polarity
What feature of a membrane describes whether molecules can cross the membrane?
permeabiity
Which substances are able to cross the membrane, and what determines their ability to do so?
Certain substances, such as small molecules and ions, are able to cross the cell membrane. The ability of a substance to cross the membrane is determined by its size, charge, and solubility in the lipid bilayer of the membrane.
Why can oxygen easily cross the plasma membrane but sodium ions are unable to cross the plasma membrane?
Oxygen is a small, nonpolar molecule that can cross the plasma membrane via simple diffusion. Sodium ions, on the other hand, are charged and larger molecules that cannot easily pass through the hydrophobic interior of the plasma membrane. Sodium must rely on specific transport proteins like ion channels or pumps to cross the membrane.
How a particular molecule crosses the membrane depends in part on the molecule's size true or false?
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.

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.
What is a factor that determines whether a molecules can cross a cell membrane?
mass
What is a factor that deteremines whether a molecule can cross a cell membrane?
Usually its size and net charge.
Which is a factor that determies whether a mole can cross a cell membrane?
Lipid solubility determines if it will diffuse across. The presence of specific protein carrier molecules determines if it will be transported across the membrane.
