2. noradrenaline,
3. dopamine,
4. serotonin.

Question 5

Action and Inactivation

Neurotransmitters bind to specific receptors in the _______1_____ membrane when released into the synaptic cleft.
Secreted neurotransmitters are eliminated by re-uptake into the pre-synaptic neuron (or glial cells) by ________ and/or by specific action.

Answer 5

1. post-synaptic membrane

2. diffusion

Question 6

Action and Inactivation of neurotransmitters?

Answer 6

Neurotransmitters bind to specific receptors in the post-synaptic membrane when released into the synaptic cleft. Secreted neurotransmitters are eliminated by re-uptake into the pre-synaptic neuron (or glial cells) by diffusion and/or by specific action.
