AAll aerobic eukaryotes always
BPlant root cells in normal soil
CYeast cells producing ethanol
DAnimal muscle cells in oxygen debt
Answer & Solution
Correct answer: D. Animal muscle cells in oxygen debt
Muscle cells convert pyruvate to lactate via lactate dehydrogenase when oxygen supply is inadequate (intense exercise).
NADH is reoxidised to NAD+ so glycolysis can continue.
Yeast also makes lactate in some species but classically makes ethanol.
