Laboratory 7 Respiration: Review 91 REVIEW
REVIEW 92 8. The plastic beads were used as a in the aerobic respiration experiment. 9. Yeast can be isolated from several different environments, including soils, insects, the skin of many fruits, and even the skin of humans. Lactose, on the other hand, is a common sugar found in the milk of mammals. From an evolutionary standpoint, can you hypothesize why yeast may not have the ability to make the enzymes required to break down lactose? Carbon dioxide produced during cellular respiration can combine with water to form carbonic acid, Bromophenol blue can be used to detect changes in pH. It will remain blue in a basic solution or turn yellow in color in the presence of an acid. If you exhaled through a straw into a beaker filled with water and then tested the water with Bromophenol blue, would you predict a change in color, yes or no? 10.a. b. Explain your answer.
