What else can I help you with?
What is a protein free membrane?
a membrane with no proteins -_-
What organelle is a mucus-secreting cell that secretes a protein product?
The Golgi apparatus is the organelle responsible for modifying, sorting, and packaging proteins for secretion from the cell. In the case of a mucus-secreting cell, the Golgi apparatus would process the mucus protein and package it into vesicles for secretion.
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.
What component of a phospholipid membrane helps the cell interact with its polar watery environment?
Membrane proteins.
What are channels in the pumps in the cell membrane mad of?
These are proteins. Transmembrane proteins span the entire membrane.

What membrane protein is responsible for binding hormones that can switch on a cell?
The membrane protein responsible for binding hormones that can switch on a cell's response is typically a hormone receptor. These receptors are often found on the surface of the cell membrane and can activate signaling pathways inside the cell in response to hormone binding.
Which membrane protein is responsible for connecting cells to each other?
The protein responsible for connecting cells to each other is called cadherin. These cell adhesion proteins are found on the surface of cells and help in forming strong adhesion between neighboring cells.
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.
What are the functions of the endoplasm?
The endoplasmic reticulum is a folded membrane what moves about the cell. It extends from the nucleus to the cell membrane. It is responsible for the production of the protein and lipid. Ribosomes also make proteins.
How can you get membrane protein from E. coli?
To extract membrane proteins from E. coli, you can use different methods such as cell fractionation techniques, detergent extraction, or sonication. Once the membrane proteins are extracted, they can be further purified using methods like chromatography or gel electrophoresis. It is important to maintain proper conditions during extraction to ensure the stability and functionality of the membrane proteins.
What type of membrane protein responsible for rejection in tissue transplants?
Major histocompatibility complex (MHC) proteins, specifically MHC class I and II, are responsible for initiating an immune response against foreign tissues in tissue transplants. These proteins present antigens to T cells, triggering the immune system to recognize and reject the transplant as a foreign entity.
Why type of protein controls what goes in and out of cells?
Transport proteins are responsible for controlling what goes in and out of cells. These proteins are embedded in the cell membrane and facilitate the movement of specific molecules across the membrane. Examples include ion channels, carriers, and pumps.
