3. (30 pts) Fermentation Pathways: Write out the balanced chemical reaction for each of the following reactions listed, in accordance with the appropriate pathway given in Figure P3.1 on the next page. In each case, write only one reaction without intermediates. You may need to include hydrogen ions or molecular hydrogen, carbon dioxide, oxygen, the acetyl group or water to balance the reactions a. Pyruvic acid (CH,COCOOH) > isopropanol (CH,CHOHCH,) b. Pyruvic acid (CH,COCOOH) 2,3-butanediol (CH,CHOHCHOHCH)

Read the following choices and identify the one that is NOT correct. (A) Aerobically, oxidative decarboxylation of pyruvate forms acetate that enters the citric acid cycle. (B) In anaerobic muscle, pyruvate is converted to lactate. (C) In yeast growing anaerobically, pyruvate is converted to ethanol. (D) Reduction of pyruvate to lactate regenerates a cofactor essential for glycolysis. (E) Under anaerobic conditions pyruvate does not form because glycolysis does not occur.

1- Consider the fermentation pathways of Clostridium as diagrammed. A common goal of metabolic engineering is to focus the metabolism of the cell to yield just one or two primary products rather than the entire spectrum of products. Which of the following overall outcomes (these are not balanced reactions) could be metabolically engineered while preserving a balanced redox state (NAD+/NADH ratio)? Write Yes or No in the blank. 2ADP - 2ATP + Hexose I 2 Pyruvate NAD NADH 2 CO2...

Energetics: fermentation. In fermentation reactions, "good" electron acceptors (like O_2 and NO_3^-) are unavailable. In ethanol fermentation pathways, the electron-accepting half-reaction is written as reaction 0-5 (with CO_2 as the apparent electron acceptor) in the half-reaction handout given in class. a) Write the two half-reactions and the net reaction for glucose fermentation to ethanol. This is essentially the net reaction for ethanol formation form corn. b) What is the net Delta G degree' for this reaction, in kJ/e- eq and...
