The nerve gas sarin acts as a poison by covalently bonding to a hydroxyl group in the active site of the enzyme acetylcholinesterase. This binding results in a higher-than-normal amount of acetylcholine at a nerve synapse, resulting in muscle spasms. From this description, would you expect sarin to be a competitive, noncompetitive, or irreversible inhibitor? noncompetitive inhibitor irreversible inhibitor competitive inhibitor

n your own words and with your own diagrams, describe the catalytic reaction mechanism of the enzyme acetylcholinesterase. Discuss the functional roles of each member of the catalytic triad plus whatever other residues that you find important. Describe the actual movements of protons, and the making and breaking of bonds. What types of chemistries is the enzyme using? (what is the enzyme doing, in term of reaction
