Give an example of a substrate level phosphorylation in glycolysis again with names, structures, and enzymes. C. Draw out the ATP structure and show me where you can break the bonds and what the product for each reaction would be for a nucleophile R¹8Ö attacking ATP.
3. Ehylene glycol, the main ingredient in antifreeze, is an odorless, colorless, sweet tasting water-soluble chemical that, when ingested, is a toxic poison. The treatment for ethylene glycol poisoning involves emergency procedures that include intravenous doses of ethanol for several hours. To understand how this treatment works, you need to know that ethylene glycol is metabolized by the enzyme alcohol dehydrogenase (ADH) into four products, and these products are actual toxic agents. If this reaction can be inhibited, then the kidneys will eliminate the ethylene glycol intact before the toxins are produced. Chemist know that ADH has 100x greater affinity for ethanol than for ethylene glycol. Given your new knowledge of enzyme activity and inhibitors, speculate about the mechanism by which ethanol prevents ethylene glycol poisoning. Hint: is a non-competitive inhibitor or competitive inhibitor involved here?
