Question

What is the sequence of events during chemical synaptic transmission in the presynaptic neuron?

1) Release of neurotransmitters into the synaptic cleft, binding of neurotransmitters to receptors on the postsynaptic neuron, and generation of a postsynaptic potential
2) Generation of an action potential in the presynaptic neuron, release of neurotransmitters into the synaptic cleft, and binding of neurotransmitters to receptors on the postsynaptic neuron
3) Binding of neurotransmitters to receptors on the postsynaptic neuron, generation of an action potential in the presynaptic neuron, and release of neurotransmitters into the synaptic cleft
4) Generation of a postsynaptic potential, release of neurotransmitters into the synaptic cleft, and binding of neurotransmitters to receptors on the postsynaptic neuron

Answer 1

The correct sequence of events during chemical synaptic transmission in the presynaptic neuron is generation of an action potential, release of neurotransmitters into the synaptic cleft, and binding of neurotransmitters to receptors on the postsynaptic neuron.

Step-by-step explanation:

The correct sequence of events during chemical synaptic transmission in the presynaptic neuron is:

1. Generation of an action potential in the presynaptic neuron
2. Release of neurotransmitters into the synaptic cleft
3. Binding of neurotransmitters to receptors on the postsynaptic neuron

Once the neurotransmitter binds to the receptor on the postsynaptic neuron, it can cause a change in the postsynaptic membrane and generate a postsynaptic potential.
