Question

Two different groups of researchers are studying alternative methods of treating Parkinson's disease. 

    • Group A - is working with black widow spiders. They have determined that their venom stimulates synaptic vesicles in the presynaptic membrane to release neurotransmitters into the synapse.  The researchers have isolated an enzyme that behaves like the venom. in the synapse. 

  • Group B  -  is working with mushrooms. They have isolated a molecule in these mushrooms that is similar in structure to dopamine. The molecule attaches to the dopamine receptor sites on the postsynaptic membrane.
