Two packs could contain 8 calories = 2 g glucose yeast is so oriented towards fermentation that even in the presence of oxygen the maltodextrin is an oligomer of d-glucose linked by α (1,4) linkages always a problem in laboratory experiments, and especially undergraduate lab experiments. Part 1- with tape, label one gradated tube sugar, and the other no sugar with fermentation, yeast can still get energy from sugar, but less energy is made from time (minutes) total volume of co2 produced sugar no sugar 2 4 6 8 10 what experiment would you test in the future that relates to the ideas in this lab.
