What is a bilayer?
A lipid bilayer is a double layer membrane formed from phospholipids. Phospholipids are composed of a polar head group and non-polar fatty acid tails. The arrangement of the phospholipids makes the cell membrane permeable.
What is an example of a lipid bilayer?
An example of a lipid bilayer is the cell membrane. It is formed by two layers of phospholipids, which have a polar head and non polar tails, providing an anfoteric environment in which phospholipids arrange to form a membrane.
What kind of lipids make up the bilayer that forms the cell membrane?
Phospholipids
What macromolecules make up the cell membrane?
The cell membrane is composed of a bilayer of phospholipids, which are composed of a glycerol molecule chemically combined with a polar hydrophilic phosphate head and two hydrophobic fatty acid tails.
Do nucleic acids form much of the cell membrane?
No, in fact most of the cell membrane consist of phospholipids and proteins. Integral proteins are mostly used for transport and other functions and the phospholipids which have a polar phosphate head and nonpolar lipid (fat) tails.
The cell membrane is composed of two layers?
The lipid bilayer makes up the membrane of a cell. The lipid bilayer consists of opposing phospholipids, where the polar ends of both the top layer and the bottom layer of phospholipids face opposite directions.
Is The cell membrane is a phospholipid bilayer.?
It is often called the cell membrane because it is made up of phospholipid bilayers. It is also often called the plasma membrane. Each phospholipid joins together at the hydrophilic head, leaving the hydrophobic tail on the inside, and forming a bilayer.

Which type of molecule forms the cell membrane?
The basic structure of cell membranes is a phospholipid bilayer. Phospholipids have a phosphate group (the head) and a lipid tail.
Do nucleic acids form much of the cell membrane?
No, in fact most of the cell membrane consist of phospholipids and proteins. Integral proteins are mostly used for transport and other functions and the phospholipids which have a polar phosphate head and nonpolar lipid (fat) tails.
Why is plasma membrane called a lipid bilayer and a fluid mosaic model?
It is often called the cell membrane because it is made up of phospholipid bilayers. It is also often called the plasma membrane. Each phospholipid joins together at the hydrophilic head, leaving the hydrophobic tail on the inside, and forming a bilayer.
What makes up cells membrane?
The Cell Membrane is made up of a bilayer (double layer) of Phospholipids. These Phosophlipids are oriented by its hydrophobic (water fearing) tails while its head are hydrophilic (water loving).
What is a Phospholipid Bilayer made of?
Lipid bilayers are made up of phospholipids that have variable head groups and fatty acid chains. This lipid bilayer is known as amphipathic, meaning the hydrophilic head region of the lipid molecule is polar while the hydrophobic tail regions are non-polar. The electrical conductance of the lipid bilayer is very low, lower even than thin glass. The lipid bilayer acts as a very good electrical insulator and has direct bearing on the way in which the proteins embedded in the lipid bilayer will behave. Researchers have shown the bilayer has conductance orders of magnitude lower than that measured in the cell membrane. Demonstrating that the conductance is not performed across the lipid bilayer, it is the proteins embedded in the bilayer which perform that function.
In a plasma membrane is a hydrophilic portion oriented to the outside of the cell?
Yes, the phosphate head which are hydrophillic is facing outside the cell and inside the cell. (Its a bilayer of phospholipids, and the fatty acid tails(hydrophobic) face each other)
