respiration
Problem: What factors affects Yeast’s rate of respiration? Hypothesis: Our hypothesis is that the fructose in orange juice will cause a negative affect on the rate of respiration. Variables: Independent variable- fructose, Dependent variable- rate of respiration. ... Conclusions: Our hypothesis was that the fructose in orange juice would have a negative affect on yeast’s rate of respiration. ... I think that this experiment went as it did because fructose does not react well with yeast respiration.
