Where does the end product of Glycolysis undergoes aerobic oxidation in eukaryotes?
Options
- AOuter chamber of mitochondria.
- BInner mitochondrial membrane.
- CCytoplasm.
- DMitochondrial matrix.
Correct answer
D. Mitochondrial matrix.
Step-by-step solution
The end product of glycolysis is pyruvic acid (pyruvate), which is formed in the cytoplasm. Under aerobic conditions in eukaryotes, pyruvic acid is transported into the mitochondria. Within the mitochondrial matrix, pyruvic acid undergoes oxidative decarboxylation catalyzed by the enzyme pyruvate dehydrogenase to form acetyl-CoA, which then enters the Krebs cycle for complete aerobic oxidation. Therefore, the aerobic oxidation of the end product of glycolysis occurs in the mitochondrial matrix. Answer: Mitochondria
