Listed below are the individual events that make up chemical synaptic transmission.1. Diffusion of transmitter across the synaptic cleft2. Depolarization of the presynaptic terminal3. Vesicle fusion with plasma membrane4. Opening of voltage-gated ion channels5. Activation of presynaptic, calcium-sensitive proteinsWhich sequence represents the correct ordering of these events?Group of answer choices1; 2; 3; 4; 52; 4; 5; 3; 12; 5; 4; 3; 15; 4; 2; 3; 11; 2; 4; 5; 3

Place the following events in excitatory synaptic transmission in order: 1 - A postsynaptic potential is produced. 2 - Voltage-gated calcium channels open and calcium enters the cell. 3 - ACh is released and diffuses across the axon terminal. 4 - A nerve signal arrives at an axon terminal. 5 - Ligand-gated sodium channels open and sodium enters the cell.

Signaling in the chemical synapse is considered:

What is the correct order for the events of neurotransmitter release from the synaptic terminal? 1) Extracellular Ca2+ enters terminal and binds to sensor protein in the cytoplasm2) Exocytosis of neurotransmitter into synaptic cleft3) Action potential reaches axon terminal4) Ca2+-protein complex stimulates fusion of the docked synaptic vesicle with the plasma membrane5) Voltage-gated Ca2+ channels open
