Step 4 of Citric Acid Cycle



Good Job! You're half way through the cycle
This is our 2nd Oxidative Decarboxylation reaction, converting Alpha-Ketoglutarate, CoA-SH, and NAD+ to Succinyl CoA, NADH, and CO2




In the next step, some form of energy will be produced.


Choose the correct reactant(s), product(s), and reaction to proceed



Reactants: Succinyl CoA, ATP --> Products: ADP + Pi, Succinate. (Oxidation Rx)
Reactants: Succinate, ADP, Pi --> Products: ATP, Succinyl CoA. (phosphorylation)
Reactants: Succinyl CoA, GDP(ADP), Pi --> Products: Succinate, GTP(ATP), Coenzyme A. (Subtrate Level Phosphorylation)
