Neurophysiology of Nerve Impulses Activity 8: Chemical Synaptic Transmission and Neurotransmitter Release (20 points total)
Notes:
• After reading the Overview and Introduction, Click on Experiment.
• Follow the directions on the left side of the menu to complete the lab. Use the data chart to answer the following questions. You do not have to submit your lab to be recorded.
Lab Analysis Questions (5 points each)
1. What is the purpose of a neurotransmitter?
2. Which chemical has the greatest effect of neurotransmitter release?
3. Why does the stimulus intensity affect the amount of neurotransmitter release at the axon terminal?
Connections to Human Physiology
1. Considering what you have learned about chemical synapses and neurotransmitters, why is it important to ingest adequate amounts of calcium? If there is not enough circulating calcium in the bloodstream, where will the calcium come from? Why would this be problematic?
Endocrine System Physiology Activity 2: Plasma, Glucose, Insulin and Diabetes (20 points total)

Lab Analysis Questions (5 points each)
1. Explain how a glucose standard curve can be used to determine the concentration of glucose in a sample.
2. According to the glucose standard curve you generated in this activity, estimate the optical density of a solution with a glucose content of 15 mg/deciliter, and explain your answer.
