Osmosis can only occur if water travels through the what?
Osmosis can only occur if water travels through the semi-permeable membrane. This will cause water to cross the lipid bilayer.
What process requires membrane proteins but not energy?
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.
Why can co2 and o2 cross the phospholipid bilayer without help from proteins?
O2 and CO2 are both nonpolar molecules, therefore they can easily pass through the hydrophobic interior of a membrane.
What process do water molecules cross the cell membrane?
Process in which water molecules moves across a membrane?
What is the sequence that represents the cross section of a bilayer?
hydrophillic head, hydrophobic tail, hydrophobic tail, hydrophillic head
Osmosis can only occur if water travels through the what?
Osmosis can only occur if water travels through the semi-permeable membrane. This will cause water to cross the lipid bilayer.
What substances will cross the cell membrane through osmosis?
Only water is transported through the process of osmosis.
Gases such as oxygen and carbon dioxide cross the plasma membrane by?
passive diffusion through the lipid bilayer
Are non polar molecules able to cross lipid bilayer?
Yes, Since the lipid bilayer of cells is nonpolar, only non-polar substances can pass directly through the bilayer without the need for any help by membrane transport proteins.
Are ions able to cross the lipid bilayer?
Yes, it is possible.
What process requires membrane proteins but not energy?
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.
What can pass through the bilayer with ease?
Molecules that are not polar or ion molecules. That is because they won't be stopped by the hydrophobic tails and they will have the acknowledgement to pass through the cell membrane thanks to little resistance. This makes those molecules have an advantage.
What are the materials required for osmosis?
Osmosis occurs when there are two solutions of different concentration strength separated by a semipermeable membrane. The membrane must allow water to cross, but not the solutes. Water will then move from the solution of lower concentration strength across the membrane to the solution of higher concentration strength. This movement of water is called osmosis.
What is the process where in the diffusion of water cross a cell membrane?

Which sequence represents a cross section of the bi-layer?
Hydrophobic head and tail is the sequence that represents a cross of the bilayer. This is all the same member. this is bull
