12 Responses to âDreams About Triplets: An Interpretation of the Triplets Dreamâ. 1  Well it wasnt exactly MY dream, but my cousin who lives about 350 miles from us called me on a Sunday and said, your not going to believe this, I dreamt you were having triplets!
Proteins are very important molecules in our cells and are essential for all living organisms. By weight, proteins are collectively the major component of the dry weight of cells and are involved in virtually all cell functions. Each protein within the body has a specific function, from cellular support to cell signaling and cellular locomotion. In total, there are seven types of proteins, including antibodies, enzymes, and some types of hormones, such as insulin.
Best Answer: Specific proteins embedded in the cell membrane can act as molecular signals that allow cells to communicate with each other. Protein receptors are found ubiquitously and function to receive signals from both the environment and other cells. These signals are transduced and passed in a different form into the cell. For example, a hormone binding to a receptor could open an ion channel in the receptor and allow calcium ions to flow into the cell. Other proteins on the surface of the cell membrane serve as markers that identify a cell to other cells. The interaction of these markers with their respective receptors forms the basis of cell-cell interaction in the immune system.
