Exocytosis is the process where a presynaptic neuron is depolarized, causing vesicles to release neurotransmitters stored inside into the synaptic cleft. The neurotransmitters then attach to receptors on the postsynaptic neuron, diffusing out of the synaptic cleft. Multiple stimuli occurring simultaneously in nearby locations can trigger this process of chemical transmission between neurons.

1. Consider the steps of chemcial transmission, which of the following describes Exocytosis The
presynaptic neuron is depolarized, and the vesicles release its stored neurotransmitters into the
synaptic cleft. Once neurotransmitters attach to receptors on the postsynaptic neuron, they
diffuse out of the synaptic cleft The sodium and potassium channels (gates) open, thanging the
potential of the membrane Multiple stimuli occuring simultaneously in nearby locations
