Here are the correct responses to your questions regarding cellular respiration and fermentation:
1. During cellular respiration, which molecule is broken down?
- **sugar**
2. During cellular respiration, four total ATP are produced when pyruvic acid is created. What else is produced as a result of this reaction?
- **water**
3. Why does hydrogen bond so tightly to oxygen during cellular respiration?
- **It is less electronegative than oxygen.** (Please note that hydrogen doesn’t bond tightly to oxygen; rather, oxygen is more electronegative than hydrogen, resulting in polar covalent bonds.)
4. Identify the byproduct of lactic acid fermentation.
- **lactic acid**
5. When a reaction releases more energy than it uses, it is called:
- **exothermic**
