Q: This compound promotes the dephosphorylation and activation of enzyme HMG-CoA to favor cholesterol synthesis and a phenylalanine for leucine substitution at residue B25 results in its "Chicago" variety. Its biosynthesis involves an excision of the C-peptide, and the compound functions by binding to tyrosine kinase receptors on cell surfaces. Sanger's improvement upon the methods of Edman degradation involved its sequencing, and its production occurs primarily in beta cells on the islets of langerhans. For ten points, name this pancreatic counterpart of glucagon used to regulate blood sugar, deficiencies of which are found in sufferers of diabetes.

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.
