| A | B |
|---|
| aerobic | requiring oxygen |
| anaerobic | without oxygen |
| fermentation | this occurs instead of aerobic respiration when cells lack oxygen |
| aerobic respiration | this is the process of breaking down glucose to release energy |
| glucose | sugar that contains energy needed for cellular respiration |
| oxygen | must be present for aerobic respiration to occur |
| water | a product of cellular respiration that is reused by the cell |
| carbon dioxide | a product of cellular respiration that is released is waste |
| mitochondria | organelle where cellular respiration occurs |
| energy | this is released during cellular respiration |
| photosynthesis | this is the opposite of cellular respiratoin |
