You are investigating the effects of a new drug your lab has created. You have an intact synapse (including pre- and post-synaptic neurons) in a dish. You add the drug to the dish so that it covers the cells and observe what happens. Following electrical stimulation of the pre-synaptic neuron, you record an action potential in the pre-synaptic neuron but observe no release of neurotransmitter into the synapse. Your drug most likely affects which of the following ions? Calcium negatively charged proteins Chloride potassium

### Investigating the Effects of a New Drug on Synaptic Function

You are investigating the effects of a new drug your lab has created. You have an intact synapse (including pre- and post-synaptic neurons) in a dish. You add the drug to the dish so that it covers the cells and observe what happens.

Following electrical stimulation of the pre-synaptic neuron, **you record an action potential in the pre-synaptic neuron but observe no release of neurotransmitter into the synapse**.

Your drug most likely affects which of the following ions?

- Calcium
- Negatively charged proteins
- Chloride
- Potassium
