Question
Chapter 13, Problem 27P
Interpretation Introduction
Interpretation:
The catalytic mechanism of the digestion of acetylcholine by enzyme acetylcholinesterase should be determined.
Concept introduction:
Neurotransmitters are the endogenous chemicals that permit the neurotransmission. This acts as a type of chemical messenger which usually transmits signals to a chemical synapse.

They are re-sponsible for producing fever and inflammation and its associated pain. Prostaglandins are derived from the 20-carbon fatty acid arachidonic acid in a reaction catalyzed by the enzyme prostaglandin en-doperoxide synthase. This enzyme, a cyclooxygenase, uses oxygen to convert arachidonic acid to PGG2, the immediate precursor of many different prostaglandins (prostaglandin synthesis is described in Chapter 21). a)The kinetic data given below are for the reaction catalyzed by prostaglandin endoperoxide synthase. Focusing here on the first two columns, determine the Vmax and Km of the enzyme. b)Ibuprofen is an inhibitor of prostaglandin endoperoxide synthase.
