The proteins that are embedded within the cell membrane carry out some essential functions in the cell membrane. These proteins help in the transportation of molecules within the membrane of an organism. These proteins also enable the recognition of one cell by another. The most popular functions that the membrane proteins are well known to carry out are basically five in number.
The functions are as listed; cell adhesion, selective transportation of molecules, cell recognition, signaling, and energy transduction. The presence and function of proteins in the cell membrane enable the cell membrane to carry out essential functions, such as keeping away from the cell's toxic substances.
The membrane serves as a channel and receptor that enables the passage of some substances like nutrients, metabolic products, wastes, and ions. The cell membrane carries out some essential activities in the body that cannot be underlooked. Thus, membrane proteins are part of the success enhancements.
