What are some characteristics of excocytosis?

Answer 1

Exocytosis is a cellular process where vesicles containing substances fuse with the plasma membrane to release their contents outside the cell. This process is essential for various functions, including neurotransmitter release in neurons and hormone secretion in endocrine cells. It typically involves the packaging of materials into membrane-bound vesicles, which then undergo membrane fusion, requiring energy in the form of ATP. Additionally, exocytosis plays a crucial role in maintaining cellular homeostasis and facilitating cell communication.
