How do hydrophobic substances cross the cell membrane?
They have parenthesene and then have rape babies with each other
What is the inside of a membrane bilayer?
Hydrophobic is the inside of a membrane bilayer.
Hydrophobic layer of the cell membrane?
Plasma membrane is made of two layer of phospholipids. The outer layer is hydrophilic while inside the membrane is hydrophobic therefore plasma membrane is not a hydrophobic barrier -it regulates what enters and leave the cell.
Which molecule has hydrophilic and hydrophobic properties and would be found in plasma membranes?
That would be phospholipids. They are a major component of the plasma membrane and contain hydrophilic, as well as, hydrophobic properties.
What are the components of plasma membrane.?
Phospholipid bilayer which consist of hydrophobic tail (repelled by water) and hydrophilic head (attracted to water).The other component are cholestrol.
What is the difference between diffusion of hydrophobic substances in comparison to hydrophilic ones across the plasma membrane?
the hydrophilic easier than hydrophobic substances

What characteristic of cell membrane allows some substances to pass through them but not others?

The cell membrane is made of a double layer of?
The cell membrane is semi-permeable controlling the movement of substances in and out of the cell. It contains a phospholipid bilayer consisting of hydrophobic tails and hydrophilic heads. Also contained in the cell membrane are transport proteins.

That would be phospholipids. They are a major component of the plasma membrane and contain hydrophilic, as well as, hydrophobic properties.
Does hydrophilic substance have an easier time passing through membranes than do hydrophobic substance?
It has a harder time passing through. The inside of the membrane is hydrophobic, so something hydrophilic (water-loving), will not be liked by the hydrophobic (water-fearing) membrane.
What are the components of plasma membrane.?
Phospholipid bilayer which consist of hydrophobic tail (repelled by water) and hydrophilic head (attracted to water).The other component are cholestrol.
Facilitated diffusion moves large molecules through what?
Glucose and polypeptides.
Which part of membrane is hydrophobic?
lipids
What are the important parts of the biological membranes?
One is that it consists of hydrophobic and hydrophilic "layers." It is also semi-permeable, meaning certain substances can pass through the membrane.
