3. What are the reactants in the observed reaction? 4. What are the products in the observed reaction? 5. How do people use the fermentation powers of yeast? 6. Is the test tube a true anaerobic environment (lacking oxygen) or is it a moderately aerobic environment (presence of oxygen), as you cover it with the balloon? Explain your reasoning. 7. Over time will it become an anaerobic environment? Explain your reasoning 8. So what processes will be utilized in the environments mentioned in #'s 6 & 7, respectively? Objective 3-Investigating Photosynthesis

Explanation / Answer

Fermentation occurs under anaerobic cinditions. During tge process of fermentatio n, yeast converts carbohydrates (sugars and starches) into carbon dioxide and alcohol.

3) The reactants in the observed reaction are carbohydrates.

4) The products in the observed reaction are carbon dioxide and alcohol.

5) Fermentation powers of yeast are made use of in baking industry for baking breads and making cakes. They are also made use of in brewing alcohol.

6) The test tube is moderately aerobic.
