1. What are some differences between fermentation and cellular respiration? Which process produces more ATP? Why do some cells in the human body use fermentation?

2. Where do the bubbles in champagne come from? (Hint: In nonbubbly wines, fermentation happens with the grape juice exposed to air. In champagne, there is an extra round of fermentation during which the bottles are capped tight.)
