What does the oxidative decarboxylation of two pyruvates yield?
A) 2 G3P
B) 2 glucose molecules
C) 2 ATP + 4 CO2 + 2 NADH
D) 1 fructose-1,6-bisphosphate
E) 2 acetyl CoA + 2 CO2 + 2 NADH
Oxidative Decarboxylation
A metabolic process in which a carboxyl group is removed from a molecule as CO2, typically coupled with the reduction of NAD+ to NADH.
Pyruvates
The ionized form of pyruvic acid, a key intermediate in several metabolic pathways, including glycolysis.
Acetyl CoA
A molecule that plays a key role in metabolism, serving as a substrate for the Krebs cycle and fatty acid synthesis; it links glycolysis and pyruvate oxidation with the citric acid cycle.

Final Answer :
E
Explanation :
The oxidative decarboxylation of two pyruvates yields 2 acetyl CoA, 2 CO2, and 2 NADH. This process occurs in the mitochondria and is a key step in cellular respiration, linking glycolysis to the citric acid cycle.
