Spring 2010 form B 7. Which of the following is an INCORRECT statement about NAD + and FAD? A. NAD + transfers one hydrogen as a hydride ion and the other as a proton, whereas FAD accepts two hydrogens as free radicals. B. Only one is derived from a water-soluble vitamin. C. NAD + is generally a weaker oxidant than is FAD. D. NAD + contains a pyridine ring system whereas FAD does not. E. Reoxidation of the reduced form of NADH + H + yields more ATP than does reoxidation of FADH 2 . ALSO INCORRECT : NAD + contains the isoalloxazine ring system whereas FAD does not. CORRECT: NAD + contains the nicotinamide ring system whereas FAD does not NAD+ CONTAINS PURIDINE RING SYSTEM! !!! CHOCOHHCH 2 OPO 3 1. (3) Name the structure depicted above. Write a word equation for the reaction that produces it. . Glyceraldehyde-3-Phosphate (G3P) F-1,6-BP = DHAP + G3P 15. (4) Write a balanced word equation for the conversion of the acetyl group of acetyl CoA to carbon dioxide in isolated, respiring, and tightly-coupled mitochondria. Include any associated phosphorylations. AcCoA + 3NAD + + FAD + GDP + P i + 2H 2 O 2CO 2 + 3NADH + 3H + + FADH 2 + GTP + CoASH (4) Write a balanced word equation for the conversion of glucose to pyruvate in animal cells. Include any associated phosphorylations. Glucose + 2NAD + + 2ADP + 2P i 2 Pyruvate + 2ATP + 2H 2 O + 2NADH + 2H + (b) Glucokinase has a kinetic property that especially suits it for its role in the liver. Give that property and explain why it is important to the role of the liver. B) Glucose + ATP Glucose-6-Phosphate + ADP Unlike Hexokinase, Glucokinase is not inhibited by the product (Glucose-6-Phosphate). Given its specifity for DGlucose and activity in the liver, Glucokinase is vital during
