Hydrophilic regions of proteins protrude from both surfaces of the bilayer?
False
Do glycolipids have hydrophilic heads?
Glycolipids contain hydrophilic heads. These hydrophilic heads interact with each other and form a hydrophilic coating on each side of the bilayer point towards the polar solvent.
Is the phospholipids bilayer symmetric?
No, it is asymmetric with hydrophilic portion on the outside and hydrophobic on the inside.
Why do integral proteins stay in place in the phospholipid bilayer?
Integral proteins are able to stay in the phospholipid bilayer because of the way they fold. Proteins have both hydrophic and hydrophilic regions that correspond to the regions of the phospholipid bilayer.
Are integral proteins amphipathic?
yes it can as its outside edges stick out of the phospholipid bilayer exposing it to the watery environment (polar/hydrophilic) and part of the protein is inside the bilayer along with the phospholipid tails (hydrophobic/nonpolar).

What is a double walled with molecules that have hydrophobic tails and hydrophilic head?
Phospholipid Bilayer

When phospholipid molecules are placed in water they form bilayer membranes Describe what you think happens to cause the formation of the bilayer membranes?
The hydrophobic and hydrophilic effect. The nonpolar tails join together in the middle of the bilayer away from water and the polar heads that can tolerate water are on the outside of the bilayer.
The cell membrane is made up of phospholipids which are molecules?
The cell membrane is made of a phospholipid bilayer with the hydrophilic ends out and the hydrophobic ends in. There are globular proteins in between the bilayer that assist in transport.
Are integral proteins amphipathic?
yes it can as its outside edges stick out of the phospholipid bilayer exposing it to the watery environment (polar/hydrophilic) and part of the protein is inside the bilayer along with the phospholipid tails (hydrophobic/nonpolar).
What kind of lipid makes up the bilayer that forms cell membranes?
Phospholipids, where one end is hydrophobic and the other is hydrophilic.
What kind of lipid make up the bilayer that form cell membrane?
Phospholipids, where one end is hydrophobic and the other is hydrophilic.
What is a phosholipd bilayer?
A phospholipid bilayer is a two-layered arrangement of phosphate and lipid molecules that form a cell membrane, the hydrophobic lipid ends facing inward and the hydrophilic phosphate ends facing outward. Also called lipid bilayer.http://dictionary.infoplease.com/phospholipid-bilayer
He characteristics that best describe the tail of a phospholipid molecule are .?
The most notable characteristic is amphipathicity, meaning it is hydrophilic on one end and hydrophobic on the other. This allows it to form a bilayer, of which cell membranes are made. If a molecule were to cross through the membrane, it would need to diffuse through a hydrophilic region, a hydrophobic region, and another hydrophilic region, which is difficult for most molecules. This is why the phospholipid bilayer is a good way to separate a cell from its environment.
