Why are Polar molecules unable to go across unless?
they pass through channels in the cell membrane.
In fact polar molecules are unable to go across unless?
they pass through channels in the cell membrane
Are non-polar molecules more attracted to other non-polar molecules or polar molecules?
Non-polar molecules are more attracted to other non-polar molecules.
Which of these molecules is polar?
Which of these molecules is polar
Polar molecules behave as though they?
Polar molecules have charges that non-polar molecules do not have. It is the reason why non-polar molecules can move through the lipid bilayer quicker than the polar molecules.
Why do oil and water hate each other?
Water is polar while oils are non-polar. Molecules that are polar will mix with other polar molecules, and non-polar molecules will mix with other non-polar molecules. Polar and non-polar molecules will not mix.
What is hydrophobic substances?
fats, oils, lipids are all hydrophobic.
What can across the membrane with assistance?
large or polar molecules such as proteins, glucose or ions like Na+/K+
Why are fat soluble molecules the only molecules that permeate across a cell membrane?
Because small non polar molecules are the ones able to cross due to the fact that the membrane consists of a phospholipid bilayer where the middle is composed on non polar tails
What do dipole dipole forces do?
Hold polar molecules together
What type of molecules dissolves in water polar or nonpolar?
Polar molecules dissolve in water. The reason why polar molecules dissolve in water, but not non-polar molecules is because non-polar molecules can't form hydrogen bonds.
What would mix the best with water non polar molecules polar molecules fatty molecules symmetrical molecules?
Polar molecules are mixed better with water.
