( /25 pts) The regeneration phase of TCA cycle: succinate  oxaloacetate citrate (a) (4pts) Draw the structures of oxaloacetate and citrate in the box below. 2pts x 2 Oxaloacetate (2pts) Citrate (2pts) (b) (7pts) Below is a description of the mechanism of the reaction that yields succinate. Fill the blanks using given hints. ( 1pt x 7 ) This reaction is initiated by nucleophilic attack on (A ) of (B ) by phosphate. This results in the formation of succinyl phosphate that contains (C ). The phosphoryl group is transferred to (D ) of (E ), and succinate is released. The phosphoryl group is then transferred to (F ) to yield (G ). A. ( electrophilic atom )_ carbonyl carbon (OR thioester carbon): “carbon” is required . PART: 0.5pt for “carbonyl” or “thioester” B. ( the main substrate of this reaction )___ succinyl-CoA (OR succinyl coenzyme A) C. ( the high energy bond, as specific as possible ) carboxlic-phophoric anhydride (OR phosphoric-carboxylic anhydride) PART: 0.5 pt for “anhydride” D. ( amino acid )_ histidine (OR
