That is just another name for the cell membrane. It's main job is to keep the things that are on the inside of a cell inside, and keep what things are outside the cell on the outside. It is also called a semipermeable membrane because it can allow some things, under certain situations, to cross the phospholipid bilayer to enter or exit the cell.
The phsopholipid bilayer is the thin polar cell membrane comprised of two layers of lipids. This membrane surrounds a cell to keep substances (ions, proteins, etc) in or out of the cell, but also allow selected substances to pass through the cell membrane as required.

What is the name of the cell proteins and a lipid bilayer barrier?

Cell proteins are often referred to as integral membrane proteins or peripheral membrane proteins, depending on their association with the lipid bilayer. The lipid bilayer barrier is primarily composed of phospholipids, which have a hydrophilic head and hydrophobic tail that create a semi-permeable barrier for the cell.


Which function does the lipid bilayer component of the plasma membrane NOT provide for the cell?

The functions that the lipid bilayer component of the cell membrane does not provide for the cell are controls that exchange of mater and chemical information between one cell and adjacent cells or environment. The lipid bilayer provides an impermeable, self sealing membrane capable of dividing or fusing the cell without breaking.


What are the key differences between integral membrane proteins and peripheral membrane proteins in terms of their structure and function within the cell membrane?

Integral membrane proteins are embedded within the lipid bilayer of the cell membrane, while peripheral membrane proteins are only temporarily associated with the membrane. Integral membrane proteins have hydrophobic regions that interact with the lipid bilayer, while peripheral membrane proteins do not penetrate the lipid bilayer. In terms of function, integral membrane proteins are involved in transport, signaling, and cell adhesion, while peripheral membrane proteins often serve as enzymes or participate in cell signaling pathways.


Can CO2 diffuse through the lipid bilayer?

Yes, carbon dioxide (CO2) can diffuse through the lipid bilayer of a cell membrane.


Why can molecules that are fat-soluble permeate across a cell membrane?

Cell membranes are composed of a lipid bilayer. Cellular fluid (cytosol) and the cell's organelles are contained by the cell's membrane, which is composed of a lipid bilayer. Lipids are a type of fat. Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol.

What is the predominant component of the cell membrane is?

The predominant component of the cell membrane is phospholipids, which form a lipid bilayer structure. This lipid bilayer provides the basic framework of the cell membrane and plays a crucial role in maintaining the integrity and function of the cell.


The major component of the cell membrane?

The major component of the cell membrane is phospholipids. They form a lipid bilayer that acts as a barrier to control the passage of molecules in and out of the cell. Proteins embedded in this lipid bilayer also play key roles in cell membrane function.

Most of the surface area of the cell membrane consists of?

The cell membrane is primarily composed of phospholipids, which form a lipid bilayer. This lipid bilayer provides a barrier that separates the cell from its external environment. Proteins are also embedded within this lipid bilayer, contributing to the diverse functions of the cell membrane, such as transport, signaling, and cell recognition.
