    76. 76. FermentationWhat happens when a cell does not have enoughoxygen for respiration? the cell releases some of the energy stored in the glucose molecules ~ this is called fermentation.Like respiration, fermentation begins in the cytoplasm.
    77. 77. FermentationWhat happens when a cell does not have enoughoxygen for respiration? the cell releases some of the energy stored in the glucose molecules ~ this is called fermentation.Like respiration, fermentation begins in the cytoplasm.As the glucose molecules are broken down, energy isreleased. The difference.....the simple molecules fromthe breakdown of glucose do not move into themitochondria.
    78. 78. Instead, more chemical reactions occur in the cytoplasm.
    79. 79. Instead, more chemical reactions occur in the cytoplasm.These reactions release some energy and producewastes.
