What else can I help you with?
A researcher made an interesting observation about a protein used to build a cell's plasma membrane The final protein in the plasma membrane was slightly different from the protein made by the ER?
The observed difference between the final plasma membrane protein and the ER protein could be attributed to post-translational modifications. These modifications, such as glycosylation or phosphorylation, can alter the protein's structure and function during its journey through the cell to its final destination in the plasma membrane. This dynamic process allows cells to fine-tune protein function for specific roles in different cellular compartments.
What makes up half the mass of a membrane?
The cell membrane plays host to a large amount of protein that is responsible for its various activities. The amount of protein differs between species and according to function, however the typical amount in a cell membrane is 50%.
What is inner membrane protein and outer membrane protein How can you get membrane protein from E. coli and how to separate the inner and outer membrane protein?
Inner membrane proteins are embedded in the inner membrane of bacteria, while outer membrane proteins are located in the outer membrane. To obtain membrane proteins from E. coli, you can disrupt the cells through methods like sonication or French press, followed by using differential centrifugation to separate the inner and outer membrane fractions based on their densities. Further purification techniques such as density gradient ultracentrifugation or membrane solubilization can be used to isolate inner and outer membrane proteins specifically.
State one function of the protein molecules that are located in cell membranes?
One function of protein molecules in cell membranes is to transport molecules in and out of the cell. These proteins act as channels or carriers that help regulate the movement of substances across the membrane.
In the plasma membrane of a cell a receptor has what function?
im not 100% sure, im actually researching it now, but i found out that a receptor protein transmits messages across the cell membrane.
Where in the cell are protein pumps located and what is their function?
Protein pumps are located in the cell membrane and their function is to transport molecules across the cell membrane, regulating the movement of substances in and out of the cell.
What is a membrane protein and how does it function within the cell membrane?
A membrane protein is a type of protein that is embedded within the cell membrane. It functions by helping to transport molecules in and out of the cell, acting as receptors for signaling molecules, and providing structural support to the cell membrane.
Is protein synthesis a function of cell membrane?
No, protein synthesis is not a function of the cell membrane. Protein synthesis occurs in the ribosomes of the cell, which are located in the cytoplasm or on the rough endoplasmic reticulum. The cell membrane is mainly involved in regulating the movement of substances in and out of the cell.
Function of cell membrane protein?
They help move material in and out of the cell.
Is protein sythesis a function made by the cell membrane?
No, the site of protein synthesis is the ribosomes, free and bound. The ribosome is the " workbench " on which proteins are made. Proteins can be imbedded in the membrane and can span the membrane.
Whats the function of tethered protein?
A tethered protein is one that is not embedded inside a membrane but is suspended away from it.
What is the function of a endplasmic reticulum?
The true question is, what is the function of an Endoplasmic Reticulum? The answer is were the cell membrane is assembled and some protein.

Is membrane permeability a major function of the plasma protein in the blood?
yes, cell membranes are semipermeable.
What protein is in the sarcolemma?
A thin membrane enclosing a striated muscle fiber. Its the function of 'a cover' of a cell.
Why do cell need to use transport protein to function?
What part of the membrane helps chemical reac
