  • The breakdown of glucose into pyruvate takes place in the cytoplasm
  • Pyruvate breaks down into lactic acid/ethanol in the cytoplasm


Note: Aerobic respiration takes place in the mitochondria. While the breakdown of glucose into pyruvate also takes place in the cytoplasm, Pyruvate breaks down into CO 2 +H 2 O inside mitochondria.
