उत्तर
| (b) | No | No |
There are two pathways through which anaerobic respiration occurs. In micro-organisms such as yeast and bacteria, the glucose is broken down into ethanol and carbon dioxide, and releases very little energy. In the other pathway, glucose is broken down into only lactic acid with the release of little energy. This occurs in the muscles during strenuous exercise. Therefore, carbon dioxide is not always produced during anaerobic respiration.
