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.
What is common in the structure of all cells?
All cells have a cell membrane that encloses the cell and controls the passage of molecules in and out. They also contain genetic material in the form of DNA that carries instructions for the cell's functions. Additionally, all cells have ribosomes, which are responsible for protein synthesis.
What do all the plant cells animal cells and bacteria cells have the same?
All three types of cells have genetic material (DNA or RNA) that carries instructions for cellular function, a cell membrane that regulates what enters and exits the cell, and ribosomes responsible for protein synthesis.
Is there a membrane in a ribosome?
No, ribosomes are not membrane-bound organelles like others.
What organelles are responsible for cell-cell connection?
The main organelles responsible for cell-cell connections are the plasma membrane and gap junctions. The plasma membrane, made of lipids and proteins, allows cells to physically connect with each other. Gap junctions are specialized protein channels that allow for direct communication between adjacent cells by allowing the passage of ions and small molecules.
What type of membrane protein joins cells?
Lipo-protein membrane
What type of membrane protein anchors cells to neighboring cells and to protein filaments found outside and inside the cell?
The type of membrane protein that anchors cells to neighboring cells and to protein filaments both outside and inside the cell is known as an integrin. Integrins are transmembrane proteins that facilitate cell adhesion to the extracellular matrix and other cells by binding to specific ligands. They play a crucial role in cellular signaling and maintaining tissue structure by connecting the cytoskeleton to the extracellular environment.

How do most materials etner cells?
Through proteins in the membrane.

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.
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 do all the plant cells animal cells and bacteria cells have the same?
All three types of cells have genetic material (DNA or RNA) that carries instructions for cellular function, a cell membrane that regulates what enters and exits the cell, and ribosomes responsible for protein synthesis.
In what ways are bacterial cells and human cells alike?
Bacterial cells and human cells are alike in that they both contain genetic material, have a cell membrane that regulates what enters and exits the cell, and have the ability to reproduce and grow. Additionally, both types of cells have ribosomes that are responsible for protein synthesis.
What is the Cell surface protein that allows a cell to with other cells?
cell membrane
What is the membrane protein complexes that strengthens the adhesion between adjacent cells?
desmosomes
Is the endoplasmic reticulum a animal or plant or both?
The endoplasmic reticulum is found in both animal and plant cells. It is a membrane-bound organelle responsible for protein and lipid synthesis.
