Eksosytoosissa

Eksosytoosissa, also known as exocytosis, is a fundamental cellular process where vesicles fuse with the plasma membrane, releasing their contents into the extracellular space. This process is crucial for various cellular functions, including secretion, neurotransmission, and cell signaling. Exocytosis is a highly regulated event that involves the interaction of specific proteins and lipids on the vesicle and plasma membranes. The fusion of the two membranes is facilitated by the formation of a fusion pore, which allows the contents of the vesicle to be expelled into the extracellular environment. Exocytosis is a dynamic process that can occur rapidly and is essential for maintaining cellular homeostasis and communication with the external environment.
