Multiple Choice
Which of the following is NOT a true statement regarding exocytosis?
A
It forms intracellular vesicles from inward folding of the plasma membrane.
B
It requires fusion of vesicles with the plasma membrane.
C
It secretes large molecules out of the cell.
D
It is responsible for neurotransmitter release of acetylcholine to stimulate muscle contractions.
Verified step by step guidance1
Understand the process of exocytosis: Exocytosis is a cellular process where vesicles containing substances fuse with the plasma membrane to release their contents outside the cell.
Identify the key functions of exocytosis: It is involved in secreting large molecules, such as proteins and neurotransmitters, out of the cell.
Clarify the mechanism of vesicle fusion: Exocytosis requires the fusion of vesicles with the plasma membrane, allowing the contents to be expelled into the extracellular space.
Recognize the role of exocytosis in neurotransmitter release: Exocytosis is responsible for releasing neurotransmitters like acetylcholine, which are crucial for stimulating muscle contractions.
Differentiate exocytosis from endocytosis: Endocytosis involves the inward folding of the plasma membrane to form intracellular vesicles, which is the opposite of exocytosis.
