1. The two lipid layers may differ in specific lipid composition, and each protein has directional orientation in the membrane. The plasma membrane also has carbohydrates, which are restricted to the exterior surface. This asymmetrical distribution of proteins, lipids, and carbohydrates is determined as the membrane is being built by the ER end up on the outside face of the plasma membrane.
What else can I help you with?
Cell membranes are asymmetrical which is a most likely explanation?
Cell membrane proteins are determined as the membrane is being packaged in the ER and Golgi. or The two sides of a cell membrane face different environments and carry out different functions.
What cell has two membranes?
A eukaryotic cell has two membranes, with the outer membrane serving as the plasma membrane that surrounds the cell and the inner membrane enclosing the organelles like the nucleus, mitochondria, and endoplasmic reticulum. This double membrane structure helps compartmentalize different cellular functions and allows for more complex regulation and control of cellular processes.
Where do we find ions gradients in cell membranes?
Gradiend occurs between two places. Mainly either sides of membrane
What are the two different types of cell wall found in eubacteria?
The two different types of cell walls found in eubacteria are gram-positive and gram-negative cell walls. Gram-positive cell walls have a thick layer of peptidoglycan, while gram-negative cell walls have a thinner layer of peptidoglycan surrounded by an outer membrane.
What two structures surround cells?
The two structures that surround the prokaryotic cell are the cell membrane or plasma membrane and the cytoskeleton. All prokaryotic cells contain these.
What is membrane sidedness?
The cell membrane regulates the flow of materials in and out of the cell. Membrane sidedness is an important concept in cell biology because to gives a better understanding on how the cell membrane functions.

What is a cell membrane of?
There are multiple membranes in a cell. Two of them are the cell membrane and the nucleur membrane.
Why does a cell with a cell wall need a membrane?
A cell that has a cell wall still needs a cell membrane because the two structures have different functions. A cell wall gives the cell shape, support and protection whereas a cell membrane controls what enters and leaves the cell. Also, the cell theory states that all cells have a cell membrane.

What are two names of the cell membrane?
The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.
What is the of definition omasis and an exsample?
movement of a solvent (as water) through a semipermeable membrane (as a living cell) into a solution of higher solute concentration that tends to equilize the concentration of solute on the two sides of the membrane.
What are two words for cell wall?
Cell membrane and Cell wall are about it.
What are two structures that are common is prokaryotic and eukaryotic cells?
Two common structures found in both prokaryotic and eukaryotic cells are ribosomes, which are responsible for protein synthesis, and cytoplasm, which is a jelly-like substance where cellular activities take place.
What are the two different types of cell wall found in eubacteria?
The two different types of cell walls found in eubacteria are gram-positive and gram-negative cell walls. Gram-positive cell walls have a thick layer of peptidoglycan, while gram-negative cell walls have a thinner layer of peptidoglycan surrounded by an outer membrane.
