Which of the following triggers the exocytosis of secretory products by entering a cell in response to a specific neural or hormonal stimulus? A)K⁺ B)Na⁺ C) Ca²⁺ D) ATP

Question

Quizplus · Accepted Answer

Calcium ions (Ca2+) are typically the triggers for exocytosis in response to specific neural or hormonal stimuli. When these ions enter the cytoplasm of a cell, they bind to specific proteins in the membrane of secretory vesicles, causing them to fuse with the cell membrane and release their contents into the extracellular space. Options A, B, and D are not typically involved in triggering exocytosis.
