Question 1

How do APs use Ca2+ to signal?

Answer 1

1. depolarizing the presynaptic membrane
   and opening Ca2+ channels
2. rise in Ca2+ concentration triggers the fusion of docked vesicles into the synaptic terminal

Question 2

What are chemical synapses ideal for?

Answer 2

To permit one neuron to rapidly and effectively excite or inhibit the activity of another cell

Question 3

What three proteins make up the SNARE complex?

Answer 3

Synaptobrevin/VAMP, Syntaxin, SNAP-25

Question 4
