The cell membrane is made up of many different kinds of proteins. These proteins can be classified as either peripheral, transme
mbrane, or lipid-anchored proteins. Regardless of their classification, these proteins all play an important role in the function and integrity of a cell. Which of the following properly describes the function of membrane proteins? a. to allow for cell-cell communication
b. to serve as a channel for the transport of molecules between extracellular and intracellular fluid
c. to provide structural stability for the cell
d. to combine with a carbohydrate, providing an immune response and/or cell recognition
Cell-cell interaction occurs in multicellular organisms. When two cells are in close approximation they form a tight junction which are multiprotein complexes that provide contact between neighboring cells. This tight junction permit calcium and other small molecules to pass through from one cell to another.
Transmembrane protein serves as ion channels for transport of ions between extracellular and intracellular fluid.
Integral proteins are deeply embedded in the bilayers and are attached by hydrophobic bonds. They contribute to the structural stability of the cell.
Carbohydrates are found on the cell surface bindings to proteins to form glycoprotein. This glycoprotein are excellent in providing an immune response, protection of cell and cell-cell recognition.
For the answer tot he questions above, the answer is "paleoanthropology"
It is also called human paleontology. It is a <span>branch of anthropology that is concerned with the origins and development of the early humans. I hope my answer helped you. </span>
