AInto the ribosomes
BInto the mitochondria
CInto the vacuoles
DInto the chloroplasts
Answer & Solution
Correct answer: B. Into the mitochondria
1. If oxygen is available, aerobic respiration goes forward after glycolysis.
2. In eukaryotic cells the pyruvate produced at the end of glycolysis is transported into mitochondria.
3. Mitochondria are the sites of cellular respiration in these cells.
4. There the pyruvate is transformed into an acetyl group and handed to a carrier compound.
