Pyruvate is accepted into the TCA cycle by a “feeder” reaction using the pyruvate dehydrogenase complex, resulting in acetyl-CoA and CO2. Provide a full mechanism for this reaction utilizing the TPP cofactor. Include the roles of all cofactors.
Map out all of the metabolic pathways in the liver cell. Draw out the structures and names of all compounds neatly by hand and the pathways responsible for metabolizing them.
Some examples are: Glycolysis/gluconeogenesis, PPP, Glycogenesis/glycogenolysis, Krebs, ETC, selectamino acid pathways (Ala, Glu, Asp) Lipogenesis/lipolysis. Citrate/MAS/glycerol phosphate shuttlesystems, and the Cori/Glc-Ala cycles.
Rules:-Draw both a mitochondrial area of metabolism and a cytoplasmic area of metabolism.-Draw the liver and its roles in glucose recycling (Cori cycle/Glc-Alanine recycling)-Avoid drawing the same molecule twice (except for separate mitochondrial/cytoplasmic populations. i.e. Design the PPP/Glycolysis so that GAP is only drawn once)-Label Carbon 4 of glucose and highlight where you would expect to find it in EVERY compound in whichit is present.-Have one or two locations for NADH/NADPH/ATP/GTP/CoQH2 – many arrows will come to/from thesespots.
a. Draw the Krebs Cycle and show the entry points for the amino acids Alanine,Glutamic Acid, Asparagine, and Valine into the Krebs Cycle. (Include name of Enzymes involved)
b. How many rounds of Krebs will be required to waste all Carbons of Glutamic Acid as CO2? (Show by drawing out the mechanism that occurs)

- The phosphate translocase is an inner mitochondrial membrane symporter that transports H2PO4- and H+ into the mitochondrial matrix. Phosphate is a substrate for Complex V (the ATP Synthase), the enzyme that couples the synthesis of ATP to the H+ gradient formed by the electron transport chain. (a) Bongotoxin is a hypothetical compound that inhibits the phosphate translocase of the inner mitochondrial membrane. Explain why electron transport from NADH to O2 stops when bongotoxin is added to mitochondria (i.e., why do electrons stop flowing through the electron transport chain even with an abundance of NADH and O 2 present). What effect will the addition of the weak acid dinitrophenol (DNP) to the cytosol have on electron transport in bongotoxin-inhibited mitochondria? Be sure to explain your answers.
