Note to moderator: Read the answerline to the last part carefully. The concentration of this molecule regulates glycolysis due to its ability to act as an allosteric activator of phospho·fructo·kinase. For 10 points each:
[10e] Name this molecule formed from the hydrolysis of the closest phospho·anhydride bond to the nucleoside of ATP. This molecule can be converted into a “cyclic” form that acts as a secondary messenger.
ANSWER: adenosine monophosphate [or AMP; accept cyclic AMP or cAMP; accept 5′-adenylic acid]
[10m] Hydrolysis of ATP into AMP produces diphosphate, which is generally referred to in biochemical contexts by this name. This ion, denoted PPi, is released upon incorporation of a dNTP into a DNA strand.
ANSWER: pyrophosphate [or pyrophosphoric acid; accept P2O74- or HP2O73-; reject “phosphate”]
[10h] Terpenoid synthesis proceeds following the formation of geranyl (“juh-RAY-nill”) pyrophosphate from these two pyrophosphate-containing isomers. These two molecules are formed at the end of the mevalonate pathway.
ANSWER: DMAPP and IPP [accept dimethylallyl pyrophosphate and isopentenyl pyrophosphate; prompt on partial answers; if a player answers phonetically (e.g., “dee-map” rather than “D-M-A-P-P”), ask them to spell their answer; reject “DMAP”]
