9.
(4 pts) Obj. 6.6 List the cellular regions where the processes occur.
PROCESS
CELL OR ORGANELLE
REGION
GLYCOLYSIS
CITRIC ACID CYCLE
LACTIC ACID FERMENTATION
ALCOHOLIC FERMENTATION
10. (2 pts) What provides the driving force for splitting glucose (glycolysis)?
6.13 Compare alcohol and lactic acid fermentation.
11. (1 pt) Does glycolysis still occur when oxygen is not present (anaerobic)?
12. (2 pts) Does glycolysis produce any ATP or high energy e- for the electron transport chain? If so, how many net ATP?
13. (1 pt) Is carbon dioxide gas (CO2) produced during lactic acid fermentation?
14. (2 pts) Is carbon dioxide gas (CO2) formed during alcoholic fermentation? (Hint: can alcohol be “bubbly”? Give an
example.)
15. (5 pts) Describe how “oxygen debt” occurs. How do we “repay” our oxygen debt?
16. (1 pt) Define obligate anaerobe (strict anaerobe).
17. (3 pts) Give two examples of facultative anaerobes. What does this mean?
18. (3 pts) 6.14 List three characteristics of glycolysis that indicate that it is an ancient metabolic system.
19. (2 pts) 6.15 Animals store most of their energy reserves as fats, not as polysaccharides. What is the advantage of
this mode of storage for a bird that migrates?
20. (1 pt) 6.16 Explain how one can gain weight and store fat even when on a low-fat diet. (Hint:
Look for G3P and acetyl CoA in fig. 6.15 and 6.16.)

6.7 – 6.12 OPTIONAL
Several analogies were used to explain the processes of cellular respiration. Fill in the blanks on the table.
Process
Analogy
Hand
games
e- transport chain
Respiratory
poisons
Garden
hose
e- transport chain
creates the proton
gradient
Bucket
brigade
Equivalents
4+2=6
6–1=5
5–1=4
Stepping down the
energy gradually instead
of leaping from the top
and hitting the bottom
Bucket = ______
Water = _____
Explanation
The sequential breakdown of carbon molecules
is simple math.
The pull of gravity vs. electronegativity
Water must be able to flow just like e- must be
accepted by oxygen. If no flow, everything
backs up and quits running.
The buckets (__) move from the water source to
the burning barn and back while the water (___)
moves in one direction, to the barn (inner
membrane space) and accumulates. (H+,
pH)
________= H+
chemiosmosis
Hydroelectric
dam
______ = inner
membrane
________ = ATP
Synthase
What provides the driving force for the following processes?
21. creating the proton gradient (electron transport chain):
22. producing ATP (chemiosmosis or oxidative phosphorylation):
23. Obj. 6.6 List the cell regions or organelle regions where the processes occur. Use whichever is more specific!
PROCESS
ELECTRON TRANSPORT CHAIN
OXIDATIVE PHOSPHORYLATION
