Question

Quizplus · Accepted Answer

"Kiss and run" refers to the process in which synaptic vesicles release only a portion of their contents into the synaptic gap before quickly retreating and being recycled back into the presynaptic terminal. This process allows for faster and more efficient communication between neurons compared to the slower and more energy-intensive process of full exocytosis and endocytosis of vesicles.
