Put the following events in the correct order 1 Synaptic ves

Put the following events in the correct order: 1) Synaptic vesicles fuse with the presynaptic membrane 2) Synaptotagmin changes its three-dimensional configuration 3) Neurotransmitter bind to receptors 4) Calcium enters the presynaptic cell through voltage-gated calcium channels 5) Action potential changes voltage in the presynaptic cell

Solution

5. Action potential reaches presynaptic cell and changes it\'s voltage.

4. Calcium gates in the membrane opens up and calculus influx starts in the axon.

2. Synaptotagmin changes it\'s three dimensional configuration. This chemical is important for docking of early synaptic vesicles to the presynaptic membrane.

1. Vesicle containing neurotransmitter substances fuse with synaptic membrane.

3. Neurotransmitter diffuses across the membrane and binds to specific receptor proteins.

So correct order is 5-4-2-1-3.
