Is it true that proteins at the inner surface of the plasma membrane attach the membrane to the cell's support structure making the cell rigid?
Your question is unclear, but a cell is supported by the cytoskeleton.
Is it true that proteins at the inner surface of the plasma membrane attach the membrane to the cells support structure making the cell rigid?
The primary proteins of cellular structure (such as in microfilaments or intermediate tubules) is myosin and actin, and sometimes collagen, and all of these are proteins in the cell. Because proteins generally connect to similar structures (aka other proteins), and the cellular membrane must SOMEHOW be attached to the primary cell structure, and it is easier to connect to the inner membrane than outer, the answer is yes.
Do proteins at the inner surface of the plasma membrane attach to the membrane to the cells support the structure?
yes
What is intergral proteins?
Integral proteins are membrane proteins that are permanently attached to the membrane phospho lipid bilayer.ATPase enzyme is an example for the integral proteins which make ATP. Peripheral proteins in contrast present on the surface of the membrane.
What the structure of the rough endoplasmic reticulum?
It contains flattened sacs called cisternae. Ribosomes are attached to outer surface of its membrane. It is specialized to synthesize proteins.
Structure of a membrane?
Every cell membrane consists of phospholipid bi layer, specialized proteins, cholesterol and glycolipids.Every plasma membrane maintains a membrane resting potential across its surface. Sometimes clusters of cholesterol called lipid rafts are also found.
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.
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).
What proteins in the cell membrane identify your cells?
cell-surface markers
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.
How does prokaryotic cells secrete proteins?
Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane.
What are indentations on the surface of a plasma membrane that contain receptor proteins?
coated pits. :)
