Q: This composer reworked an instrumental sarabande into the aria Lascia ch'io planga. He called for improvised solo organ pieces to be placed ad libitum into the later of his organ concertos, a genre he invented to show off. The "Hailstone Chorus" appears in the first part of an oratorio by this man whose second part is "The Song of Moses"; that work is Israel in Egypt. One of this man's works includes a suite in G major that has a rigaudon, a minuet, and five shorter, unnamed pieces, as well as a suite in F major that begins with a (*) French overture. That piece was written to be played on barges floating on the River Thames for King George I. For 10 points, name this Baroque composer who wrote Water Music and the oratorio Messiah.

Q: This pathway is inhibited by a deficiency that causes a precursor molecule to be lacking, known as Tauri's Disease, which is a deficiency of the Phosphofructokinase enzyme. A reverse of this reaction is used by bacteria to synthesize carbon compounds from CO2 and water. Its third step sees cis Aconitate attacked by Aconitase and hydrated to release water. Its ninth step sees an addition reaction between Fumarate and the Fumarase enzyme. During its first turn, it produces one GTP, three NADH, one FADH2, and two CO2. FTP, name this pathway, occurring directly before the electron transport chain in cellular respiration, also known as the Citric Acid Cycle.

Q: This element can be detected in a test that uses strips of paper sensitized with mercuric chloride placed in a bottle containing granulated zinc, water, and hydrochloric acid. Another test for this element precipitates metallic silver out of a silver nitrate solution after a compound containing this element is reacted with nascent hydrogen. Those tests, named respectively for Gutzeit and Marsh, are used to distinguish this element from antimony. Paul Erlich developed syphilis-treating drugs containing this element, such as atoxyl and Salvarsan. More modern drugs containing it include Mel B, which is used to treat trypanosomiasis, or sleeping sickness. People who were given it tended to have brick red-colored mucosa on the post-mortem. For 10 points, name this element famed as a poison.
