What else can I help you with?
What molecules in membrane give them their specific function describe activities of one of these molecules?
Phospholipids are the main molecules in membranes that give them their specific functions. They can form a hydrophobic barrier due to their structure, allowing the cell to control what enters and exits. One activity of phospholipids is their ability to spontaneously self-assemble into a bilayer structure, providing stability and flexibility to the cell membrane.
What is the of a cell membrane in an animal cells?
if you are talking about function, it is to control what get in and out of a cell and to give the cell a shape
What is the function of a cell mebrane?
what the cell membrane does is give the cell it's shape and prevents thing from come in into it and out
What role do membranes play in prokaryotic cells in eukaryotic cells?
Membranes in both prokaryotic and eukaryotic cells help compartmentalize the cell and regulate the passage of molecules in and out of the cell. In prokaryotic cells, membranes are also important for energy production and cellular processes. In eukaryotic cells, membranes play a critical role in organelle structure and function, as well as in cell communication and signaling.
What important ability to phospholipid by-layers give to cell membranes?
Phospholipid bilayers provide selective permeability to cell membranes, allowing them to regulate the passage of substances in and out of the cell. This ability helps maintain internal conditions, such as ion concentrations, necessary for cellular function. Additionally, the fluid nature of phospholipid bilayers allows for membrane flexibility, which is essential for cell movement and shape changes.
What life function does cell membrane do?
regulation execration transport I'm too lazy to give detail -_-
Do proteins at the inner surface of the plasma membrane attach to the membrane to the cells support the structure?
Yes, proteins at the inner surface of the plasma membrane can attach to the cytoskeleton of the cell, providing support and helping to maintain the structure of the membrane. These membrane-associated proteins interact with the cytoskeleton to anchor the membrane in place and facilitate cell shape and movement.
What is the lipid that is most abundant in all cell membranes?
Phospholipids are the most abundant lipids in cell membranes. They consist of a hydrophilic head and two hydrophobic tails, which give them the ability to form the lipid bilayer that makes up cell membranes.
How do properties of lipids help explain the structure of the cell membrane?
Lipids do give cells membranes a flexible structure that forms a strong barrier between the cell and the cell surroundings. Hence, the lipid surrounds the structure which then forms the shape of the cell.
Do all cells have a cell membrane?
All cells need a membrane. The membrane helps with keeping in all the fluids and organelles plus it takes in and sends out important things. Plant cells and bacteria have cell walls which give an extra layer of protection.
Does cholesterol serves no function in the cell?
It functions by serving its purpose of being in the plasma membrane. Which is to give the membrane more fluidity in normal and low temperatures and to prevent the membrane from being too fluid in high temperatures in respect to the membrane.
Major functions of cell membrane proteins?
Examples of proteins in the cell membrane are pore/channel proteins, carriers, glycoproteins. Therefore protein assist in transport of substances across cell membrane. Cell recognition. Involved in mechanical strength and attachment of the cell membrane ( protein substances surround the cell membrane that allows it to attach to other cells)
