The following are partial equations representing acid-base reactions. Looking carefully at the connectivity of the atoms shown in the equation and at the conjugate acid-base pairs found in the pKa table, construct structural formulas for the missing species designated by letters. Indicate the direction of the equilibrium in each case by the relative sizes of the reaction arrows. For each...
A) Write the overall reaction for step 5 of the TCA Cycle (succinyl-CoA -> succinate), showing structures for succinyl- CoA and succinate. Be sure to include the other molecules that take part in this step (there should be another reactant besides succinyl-CoA and two other products besides succinate). B) Step 5 is an example of an acyl transfer reaction. Circle...
