Question: Earthworms uniquely use the molecule lombricine to react with this molecule. This molecule activates P2X3 and P2X2/3, two receptors that control pain responses, and in conjunction with luciferin this molecule is responsible for the light of fireflies. In the muscular tissue of chordates, this compound donates a group to creatine. In proteins, this molecule, first synthesized by Alexander Todd, is almost always bound by a magnesium cofactor, and large quantities of this molecule are produced via oxidative phosphorylation in the electron transport chain. For 10 points, name this molecule discovered by Karl Lohmann,, the energy currency of the cell.

Answer: Science

Question: In contrast to the internal, or L1 type, the L2 type sits between the CPU and DRAM, but both L1 and L2 are made of high-speed SRAM for the memory type. This disk type actually uses main memory, but stores information in a memory buffer. The original Pentium processor had a 16 kilobyte one of these built into it. FTP, name this high-speed storage mechanism that keeps frequently accessed data in a location separate from the main memory for rapid recall.

Answer: Science

Question: This composer has the cellos play half pizzicato, half arco over a sustained "D-A-C-sharp" drone in the first movement of one piece. The second movement of that piece by this composer begins with a high cello solo and includes a celesta ostinato. He included a "Praludium" marked "Rasch" in his sort-of-neo- baroque Piano Suite. Another piece by this composer includes a "Valse de Chopin" and uses an "E-G-E- flat" motive in a movement subtitled "Passacaglia." He originally used titles like "The Obbligato Recitative" and "Chord Colours" for his Five Orchestral Pieces, in which he made the first major use of Klangfarbenmelodie. Another piece by this composer uses a different combination of piano, flute, clarinet, violin, and cello in each movement and is a setting "three times seven poems" by Albert Giraud using sprechstimme. For 10 points, name this Second Viennese School composer who innovated atonality with pieces like his Three Piano Pieces, Opus 11, and Pierrot Lunaire.
