What happens to the membrane of a vesicle after exocytosis?
A
It forms a new vesicle inside the cell.
B
It is expelled from the cell.
C
It is degraded by lysosomes.
D
It becomes part of the plasma membrane.
검증된 단계별 안내1
Understand the process of exocytosis: Exocytosis is a cellular process where materials are exported out of the cell via vesicles. These vesicles fuse with the plasma membrane to release their contents outside the cell.
Identify the role of the vesicle membrane: During exocytosis, the vesicle membrane becomes part of the plasma membrane. This is because the vesicle fuses with the plasma membrane, integrating its lipid bilayer into the cell's outer membrane.
Consider the options given: Analyze each option to determine what happens to the vesicle membrane after exocytosis.
Evaluate the correct option: The correct answer is that the vesicle membrane becomes part of the plasma membrane, as this is a key aspect of the exocytosis process.
Conclude with the biological significance: This integration of the vesicle membrane into the plasma membrane helps maintain the size and integrity of the cell's membrane, allowing for continuous cellular processes and communication.
