What triggers the exocytosis of secretory products by entering a cell in response to a specific neural or hormonal stimulus

Question

Quizplus · Accepted Answer

Calcium ions are the primary trigger for exocytosis, as they bind to specific proteins on the membrane of secretory vesicles, resulting in fusion of the vesicle with the plasma membrane and release of its contents into the extracellular space. K⁺, Na⁺, and ATP do not directly trigger exocytosis of secretory products.
