1. Which gas is given off by cell respiration? Carbon dioxide2. Which gas is produced as a result of fermentation of yeast cells Carbon
dioxide
3. Which of the following describes the structure of a disaccharide Two
monosaccharides bonded together
4. Which type of process is alcoholic fermentation Anaerobic
5. The cell respiration pathway that occurs in the mitochondria is Aerobic
6. Which of the following is an endergonic (energy-requiring) reaction? ADP +
P -> ATP
7. Glucose is an example of which type of carbohydrate Monosaccharide
8. Which carbohydrate is the primary or preferred starting compound for
glycolysis and the fermentation pathway Glucose
9. Using the respirometer, how can you determine which carbohydrate is used
most of sufficiently buy used for fermentation? The solution in the tube with
the largest gas bubble has fermented most efficiently
10. Hypothesis: how easily do you think the following substrates are fermented by
yeast? glucose is the easiest, then sucrose, fructose and starch. water is not
fermented.
, 11. Strategy: what will you measure to determine the fermentation speed? the
height of the CO2 bubble produced
12. Strategy: What test solutions will you prepare to test which sugar is fermented
most easily by yeast? yeast and one sugar in each test tube plus a distilled water
control
13.why is distilled water used in this experiment? it has no sugar, so it is an
experimental control
14.why is it important to stir the yeast before adding it to the test tubes? to
make the yeast concentration is uniform so all the samples get the same
amount
15.which of the fermentation products produced by yeast is a gas? carbon
dioxide
16.which product of yeast fermentation is used in the beer-making industry?
carbon dioxide and ethanol
17.what will cause the size of the space in the top of the small tube to change in
volume? an increase in the production of carbon dioxide from fermentation
18.how will you know if one sugar is fermented more easily than another? The
space in the top of the small tube will increase in volume more quickly
19.what would happen if you let the respirometers incubate at room temperature
instead of 37 degrees C? fermentation would still occur, but more slowly
