Krebs Cycle Puzzle: Concept Map of Oxidation/Reduction Reactions: Pyruvate is converted Acetyl CoA by the removal of one CO2 group. 1. The two carbon Acetyl CoA is added to a 4 carbon compound producing a 6 carbon compound called citric acid (citrate). A separate reaction isomerizes the citrate to isocitrate. Acetyl Co-A Step 1 6 C compound Step 2 2. The isomerized form of citrate has a CO2 group removed, and the resulting 5 carbon compound is then oxidized, reducing the coenzyme _______________ to __________________. 5 C compound Step 3 3. This is a complex step since three different things happened to the 5 carbon compound. (1). A CO2 group is removed. (2).The resulting 4 carbon compound is then oxidized, reducing the coenzyme_______________ to _________________. (3). Then a coenzyme called C0-A-SH is unstably bonded to the 4 carbon compound. 4 C compound Step 4 4. The 4 carbon compound has the C0-A-SH group removed, and the Co-A-SH group is replaced by a PO4 group. The PO4 group is then transferred to GDP producing GTP. GTP transfers the PO4 group to ADP producing ________________. 4 C compound Step 5 5. The 4 carbon compound is oxidized, reducing FADH to ___________________. The removal of the H during oxidation produces a compound with a double bond in the carbon backbone. 4 C compound Step 6 6. A water molecule is added which rearranges the bonds in the 4 carbon compound, and removes the double bond. 4 C compound Step 7 7. The 4 carbon compound is again oxidized, reducing the coenzyme _________________ to __________________. The product of this reaction completes the cycle since it can now join with another Acetyl C0A and enter at step 1 of the cycle. 4 C compound
