A membrane protein is made and inserted into the membrane of the rough ER. The protein is then glycosylated. If this protein is then moved to other endomembranes, at which surface of the membranes given is this protein region unlikely to be found? a. Cytosolic face of the plasma membrane b. Internal face of the Golgi apparatus membranes O c. Lumenal face of a vesicle just derived from the trans Golgi O d. Facing the intermembrane space of the nuclear envelope membranes e. Internal face of a lysosome membrane
Structure and Composition of Cell Membrane
Despite differences in structure and function, all living cells in multicellular organisms are surrounded by a cell membrane. Just like the outer layer of the skin separates the body from its environment similarly, the cell membrane, also known as 'plasma membrane,' separates the inner content from its exterior environment.
Cell Membrane
The cell membrane is known by different names like plasma membrane or cytoplasmic membrane, or biological membrane. The term "cell membrane" was first introduced by C. Nageli and C. Cramer in the year 1855. Later on, in 1931, the term "plasmalemma" for cell membrane was given by J. Plowe. The cell membrane separates the cell's internal environment from the extracellular space. This separation allows the protection of cells from their environment.
Prokaryotes vs Eukaryotes
The cell is defined as the basic structural and functional unit of life. The cell membrane bounds it. It is capable of independent existence.
