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.
What protein that projects from the outer surface of the membrane is termed?
The protein that projects from the outer surface of the membrane is termed as an extrinsic or peripheral membrane protein. These proteins are not embedded within the lipid bilayer but instead are attached to the surface of the membrane.
What cellular structure has been described as a sea of lipids with protein icebergs?
Cell membrane, also known as plasma membrane, has been described as a sea of lipids with protein icebergs. The lipid bilayer forms the sea, while the proteins embedded in or attached to the lipid bilayer are the "icebergs" that float within it.
What protein stay on one side of the bilayer?
Integral membrane proteins are proteins that span the entire lipid bilayer and stay associated with one side of the bilayer, either the inner or outer side. These proteins have hydrophobic regions that allow them to anchor into the membrane.
What is the difference between peripheral and integral proteins?
Peripheral proteins are under the phospholipid bilayer, while integral proteins are inscribed in the bilayer.Integral proteins pass entirely through the lipid bilayer of the plasma membrane and have domains that go from the outside of the cell to the cytoplasm inside the cell. While peripheral proteins are only on the one side of the lipid bilayer, either the outside of the cell or the cytoplasmic side inside the cell, but not both.
What is another name for the phospholipid bilayer?
It depends on which lipid bilayer you're talking about. There is the phospholipid bilayer that surrounds eukaryotic cells, cholesterol phospholipid bilayers, protein lipid bilayers, phase transition lipid bilayer, lipid bilayer membrane...
Where in a cell does the production of protein carbohydrate and lipid molecules occur?
Protein= Ribosomes. Carbohydrate= Plasma Membrane Lipid= Lipid Bilayer
Hydrophobic interactions of the tails of phospholipids can produce a. a cytoskeleton. b. a protein membrane. c. a nonpolar membrane. d. a lipid bilayer. e. hydrolysis of the fatty acid?
c. a nonpolar membrane
Why do proteins remain embedded in the lipid bilayer?
Proteins remain embedded in the lipid bilayer due to hydrophobic and hydrophilic interactions between the protein's amino acids and the lipid molecules. The hydrophobic regions of the protein interact with the hydrophobic fatty acid tails of the lipid bilayer, while the hydrophilic regions interact with the hydrophilic lipid head groups. This arrangement helps stabilize the protein within the membrane.

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.
What protein that projects from the outer surface of the membrane is termed?
The protein that projects from the outer surface of the membrane is termed as an extrinsic or peripheral membrane protein. These proteins are not embedded within the lipid bilayer but instead are attached to the surface of the membrane.
What organelle is composed of a phospholipid bilayer?
The organelle that is composed of a phospholipid bilayer is the cell membrane. It surrounds the cell and acts as a barrier, controlling what substances can enter and leave the cell.
Whattype of bilayer makes up most of the cell membrane?
lipid bilayer
What is the difference between peripheral and integral proteins?
Peripheral proteins are under the phospholipid bilayer, while integral proteins are inscribed in the bilayer.Integral proteins pass entirely through the lipid bilayer of the plasma membrane and have domains that go from the outside of the cell to the cytoplasm inside the cell. While peripheral proteins are only on the one side of the lipid bilayer, either the outside of the cell or the cytoplasmic side inside the cell, but not both.
What is lipid bilayer?
thin membrane made of two layers of lipid molecules.
How does lipid soluble move across the plasma membrane?
by dissolving in the lipid bilayer.
How does a plasma membrane determine selectivity of molecules?
The plasma membrane is selectively permeable due to its structure and composition. It contains proteins and lipid molecules that control the passage of substances into and out of the cell. These proteins can act as channels, carriers, or pumps that determine what molecules are allowed to pass through the membrane based on size, charge, and shape.
