Refer to the figure showing a neuromuscular junction. Which cellular event is paired correctly with the location where it occurs?
A) At position 2, calcium ions trigger fusion of vesicles with the presynaptic membrane.
B) At position 3, voltage-gated calcium channels open.
C) At position 4, acetylcholine molecules diffuse across the synaptic cleft and bind to receptors on the postsynaptic membrane.
D) At position 6, acetylcholine is broken down and the components are recycled.
E) At position 7, neurotransmitter is released.
