Some guiding thoughts for the Fermentation and Respiration Lab Intro’s. Preparing the Introduction for the Fermentation and Respiration lab is fairly straight forward. The supporting facts for hypotheses about questions 1 & 2 can be derived from much of what you have learned so far in lecture and lab. Facts related to the Enzyme Lab are particularly relevant. However, these cannot be used without reference as to how they apply to yeast cells. I feel that you should have no difficulty coming up with the necessary supporting facts for these questions – especially if you made a sincere effort on the first introduction. Question 3 is much more challenging; here you need to think about how yeast cells and corn seedlings compare as organisms . Points of comparison include: • What are the differences between the composition of the food source for the two organisms? • What are the differences between the localization of the food source for each of the two organisms in comparison to where it is used? In other words, how far do the substrates for
