After a neurotransmitter is released from an axon terminal, what are three things that can happen to it?
 
  What will be an ideal response?

Question 2

What does depolarization in a neuron refer to?
 
  What will be an ideal response?

Answer to Question 1

1. Bind to post-synaptic receptors
2. Bind to autoreceptors
3. Undergo reuptake into axon terminal or
4. Uptake into glial cells
5. Diffuse through extracellular fluid
6. Undergo enzymatic degradation

Answer to Question 2

It refers to a shift in a neuron's membrane voltage potential, generally from its resting potential of approximately -70 mV towards 0 mV. During an action potential, this depolarization actually involves a shift from its resting potential beyond 0 mV to around +30 mV.
