Question

Exocytosis is the process that results in 
A)the generation of action potentials. 
B) the release of neurotransmitters by the presynaptic neuron.​ 
C) reuptake of released neurotransmitter substance.​ 
D) the interaction of a molecule of neurotransmitter and a receptor site.​

Quizplus · Accepted Answer

Exocytosis is the process by which neurotransmitters are released from the presynaptic neuron into the synaptic cleft to interact with receptors on the postsynaptic neuron. Thus, option B is the correct choice. Option A is incorrect because it refers to the generation of action potentials, which is a separate process from exocytosis. Option C is incorrect because it refers to the reuptake of neurotransmitter after it has been released, which is a separate process from exocytosis. Option D is incorrect because it refers to the interaction between the neurotransmitter and receptor, which occurs after the neurotransmitter has been released via exocytosis.
