B)Exocytosis
C)Pinocytosis
D)Osmosis

Question

Quizplus · Accepted Answer

Neurotransmitter is released from the presynaptic neuron to the synaptic cleft through exocytosis, which involves the fusion of synaptic vesicles containing the neurotransmitter with the presynaptic membrane, leading to the release of the neurotransmitter into the synaptic cleft. Endocytosis is the process of taking in material from the extracellular environment into the cell through invagination of the cell membrane. Pinocytosis is a form of endocytosis that allows the cell to take in small droplets of extracellular fluid. Osmosis is the diffusion of water molecules across a selectively permeable membrane from a region of high water concentration to a region of low water concentration. None of these processes are involved in the release of neurotransmitter from the presynaptic neuron.
