What 2 things make up all cell membranes?
protein and a lipid layer
Is it true that carbohydrates also make a part of the cell membrane?
No, carbohydrates are NOT a major components of cell membranes, which are mainly comprised of lipid (fat molecules). Proteins sit in and on the membrane and SOME of the proteins are glycosylated, which means that they have sugar or carbohydrate attached to them. So there are carbohydrates in cell membranes, but they are not a major component.
What specific kind of lipid is used in membranes?
Phospholipids make up the lipid bilayer.
What is used to make the lipid bilayer found in cell membranes in the body?
Lipids, or fat, is used to insulate the body and found in all cell membranes. Fats have insulating capacity, but they are bad conductors of heat.
Large biological molecules known as lipids?
A lipid is a large non polar biological molecule which is not a polymer. Insoluble in water and store energy and make up the cell membranes. So yes you are correct.

What is the major component of biological membrane?
Phospholipids make up the lipid bilayer of the cell membrane. They consist of a phosphate group, a lipid, and a nitrogenous base. The cell membrane contains two of these, with each phosphate group facing away from the other. Also, the cell membrane has proteins and cholesterol in it.

Lipids, or fat, is used to insulate the body and found in all cell membranes. Fats have insulating capacity, but they are bad conductors of heat.
What kind of lipid make up bilayer that forms cell membranes?
Phospholipids make up this layer. Phospholipids belong to the family of biological polymers.
What is the key structural element of a cell membrane?
The primary structural component of a cell membrane is the phospholid layers. This is mainly made of proteins which facilitate various cell activities.
Large biological molecules known as lipids?
A lipid is a large non polar biological molecule which is not a polymer. Insoluble in water and store energy and make up the cell membranes. So yes you are correct.
Does biological molecules proteins and lipids have cell membranes?
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
Why is a cell membrane described as a bilayer?
Phospholipids are lipids that are essential to cells because they make up cell membranes. When phospholipids are added to water, they self-assemble into double-layered aggregates, or bilayers, that shield their hydrophobic portions from water. The phospholipid bilayer forms a boundary between the cell and its external environment.
Which molecule in animal plasma membranes stiffens and strengthens the membrane?
Methionine, a sulfur-containing amino acid, is an intermediary that helps strengthen cell membranes. The infamous cholesterol that we're often advised to avoid also helps maintain the integrity of cell membranes (and to a lesser degree, the integrity of the membranes of organelles inside the cell). The cell's plasma membrane is considered a fluid mosaic where the lipid molecules in the bilayer move about in the membrane. However, cell membranes may experience transitions which make their molecules more gel-like or nearly solid.
