Based on your knowledge of Glycolysis and the TCA cycle ADD any missing substrates, products and H+ required to balance reactions 1 to 4; no information is required about reaction 5. Abbreviations may be used for vitamin-containing groups or molecules and for any molecules lacking a vitamin-derived group if it has > 5 C atoms. (4 points) (b) State the full name of the one vitamin that is involved in every reaction. (2 points) ________________________ (c) Complete the table below according to the following instructions. (12 points) (i) Indicate which Glycolysis or TCA cycle reaction each reaction on p.11 is most similar to. Specify the Glycolysis or TCA cycle reaction using the reaction number (eg. Glyco-1, TCA-3 etc, see the reference material for reaction numbers). (ii) State the 1-word systematic enzyme name. ( iii) State the full name of any vitamin(s) involved in each reaction. Do not include the vitamin from your answer to (b) since this vitamin is involved in every reaction. If a vitamin is not involved, indicate this using the word “None” Reaction Reaction similar to which Glycolysis or TCA cycle reaction? Systematic enzyme name (1 word) Names of any vitamin(s) involved in reaction 1 2 3 4 (d) In Rxn #5, a C-C bond is broken. How is the carbanion stabilized? It may be useful draw resonance structures here (4 points). Page 13 (e) Calculate the number of molecules of ATP formed when one 16-C fatty acid is converted to acetyl CoA and then oxidized completely to CO2 and H2O via the TCA cycle and the ETC. (6 points) Be sure to include ATP from both SLP and oxphos and use the experimentally-derived values for ATP yields from oxidative...
