Question

Contrast sarin’s mechanism of action with that of pufferfish toxin. Label your drawing of a neuron and the graph of an action potential where TTX and Sarin have an effect and note how.

Answer 1

Answer Sarin is the most rolatile of nerve agents , which means that in I can easily and quickly evaporate I from a liquid into a rakor and spread into environment for our nerves talk to each other by releasing of chemicals called neurotransmitters. These drempleabs Blaxo eroo vand oorgele sale and see los a doveing dus oo & age cholinesterase is enzyme which break acytyl choline neurotransmitter and conduct message as it needed. But sarin is cholinesterase inhibitors. These sarin Inhibits o this enzyme so they can't break down transmitter so transmitter stays around and keep giring its message. This may lead to death of person. on a large exposure.
