<em><u>-If no oxygen is present, what process happens during cellular respiration?
</u></em>
If no oxygen is present, cells can only utilize glycolysis to make ATP. Cells without mitochondria can only utilize glycolsis. Glycolysis couples with fermentation to produce ATP. Cellular respiration is the process cells use to make energy. Cells in our body combine glucose and oxygen to make ATP and carbon dioxide. Thus why oxygen is to be present during cellular respiration.
