What are the most important ingredient of cell membrane?
Most of the membrane is composed of phospholipid molecules. These allow the membrane to be rather fluid.Embedded in this membrane are proteins which give some structure to the membrane. The 3rd components are proteins or glycolipids. The proteins sort of float on the surface of the membrane like islands in the sea.Cholesterol is also found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity.Cholesterol is only found in animal cells.The carbohydrates that are in plasma membranes are bound either to proteins or to the lipids. They form sites on the surface that allow the cells to recognize each other.
What proteins are on the surface of the cell membrane?
The cell membrane contains many integral membrane proteins (proteins permanently attached to the surface), over the entire of its surface. These may include integrins, cadherins, desmosomes, clathrin-coated pits, caveolaes, and different structures involved in cell adhesion (the binding of a cell to the membrane surface).
Why is the cell membrane said to be a fluid mosaic?
Generally water and gases are described as fluid. In this context cell membrane is said to have a fluid mosaic model just because of it super flexible nature. Lipid bipolar molecules in the cell membrane can exhibit a flip flop movement. It can easily reseal after any breakage. So as fluid have an ease in changing their orientation likewise cell membrane posess a similar property. shankha LOL
Which part of the water hyacinth help it to float?
Leaf petiole
What protein floats in the cell membrane and receives hormonal signals sent from other cells?
Integral Proteins float freely within the bilayer of the cell membrane. They are usually transmembrane proteins, extending through the lipid bilayer. One end is in contact with the interior of the cell while the other remains in contact with the exterior. These are the only proteins that can perform functions both inside and outside the cell.

The phospholipid sea in which embedded substances float?
Gg
Are proteins the molecules that make up the membranes of cells and organelles?
Answeryes they do!, i just learned that in science great hah? Answer (improved)While proteins are a part of what makes up membranes, they are also made up of substances known as phospholipids.Proteins build up cells and control their chemical reactions by means of enzymes which is a natural catalyst.
What is meant by the statement The cell membrane is said to be fluid?
This membrane is called the fluid mosaic model as it is a mixture of phospholipids, cholesterol, proteins and carbohydrates. Most of the membrane is composed of phospholipid molecules. These allow the membrane to be rather fluid.Embedded in this membrane are proteins which give some structure to the membrane. The 3rd components are proteins or glycolipids.The proteins sort of float on the surface of the membrane like islands in the sea.
How does a needle float on water?
the way it float is surface tension!!
What type of water is most likely to float on the surface of the ocean?
Ice is a form of water that will float on the surface of the ocean.
If an object's density is is less than that of the fluid what will happen?
it will float providing it is in that fluidIt will float on the surface of the fluid.
You toss a coin into a wishing well full of a liquid denser than the coin. will the coin sink?
no, it will float on the surface
What is a wooden float?
A Wooden float is the flat surfaced tool that is used for smoothing the surface of concrete prior to it setting. A wooden float produces a reasonably non slip surface as it pulls up sand out of the concrete mix to the surface.
