The question is asking which among the given statements are false about neurotransmitters.
00:11
The first option is true and it says when the action potential reaches the exon terminal, it causes the entry of ca2 plus ions, that is the calcium ions through calcium channels.
00:34
And this is shown as this is the calcium channel.
00:41
When action potential reaches to the terminal, the ca2 plus ions enters inside the pre -synaptic neuron.
00:49
After this, there occurs the fusion of synaptic vesicles that contains neurotransmitter inside them.
01:01
That is, these vesicles fuses to the plasma membrane of pre -synaptic neuron.
01:08
As a result of which the neurotransmitters gets released into the synaptic cleft as shown in the diagram.
01:26
The second option is false which says that neurotransmitters gets degraded once they are released.
01:35
But this is not the case as neurotransmitters after their release binds to the receptors present on the post -synaptic neurons, which is shown by the green color in the diagram above.
01:56
And after binding, they generate certain response...
