Which of the following correctly describes some aspect of exocytosis or endocytosis? • View Available Hint(s) These two processes require the participation of mitochondria. Exocytosis and endocytosis temporarily change the surface area of the plasma membrane. Endocytosis and exocytosis involve passive transport. The inner surface of a transport vesicle that fuses with or buds from the plasma membrane is most closely related to the inner surface of the plasma membrane. Both processes provide a mechanism for exchanging membrane-impermeable molecules between the organelles and the cytosol.
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.
I am confused as to why (d) or (e) are not correct.
Is it not (d) because the inner surface of the vesicle becomes the extracellular component?
And what about (e)? Is it because it's not between the organelles and the cytosol, but rather between the cytosol and the extracellular space?
