Question 18

Some friends are trying to make wine in their basement. They've added yeast to a sweet grape juice mixture and have allowed the yeast to grow. After several days they find that sugar levels in the grape juice have dropped, but there's no alcohol in the mixture. The most likely explanation is that:
Answer
the mixture needs more oxygen. Yeast need oxygen to break down sugar and get enough energy to produce alcohol.
the mixture needs less oxygen. Yeast only produce alcohol in the absence of oxygen.
