The synapse ---> worksheet

Question 1

How does the conversion between electrical and chemical work

Answer 1

before the neurotransmitters are in the synaptic cleft, the process is electrical, although, once they enter the cleft, it is chemical because the gap is chemical, and then, once it enters into the post synaptic membrane, it is electrical

Question 2

What happens once action potential reaches pre synaptic membrane

Answer 2

1) action potential activates calcium gated cannels and Ca2+ diffuses into the neuron

2) the Ca2+ causes vesicles to fuse with cell membrane. Through exocytosis the neurotransmitters are released into the synapse

3)these neurotransmitters than do the usual
