Part 1 of 3 parts
1. The original/ultimate source of energy for most organisms
2. The relationship between cellular respiration and photosynthesis
3. Classification of cellular respiration & photosynthesis on basis of the type of their metabolic
pathways
4. The process by which some organisms, e.g. yeast, get their energy (ATP) from glucose in the
absence of oxygen
5. Cellular respiration:
a. Its various stages/phases
b. The cellular location where each stage/phase takes place
c. The relative energy (ATP) production efficiency of each stage/phase
d. The end product(s) of each stage/phase
e. The number of ATP molecules produced by each stage/phase
f.
Its byproducts
6. The total number of ATP molecules produced by cellular respiration vs the the number
produced by lactic acid fermentation
7. The different names of the citric acid cycle
8. The fate of pyruvate (one of glycolysis end products) in the presence and absence of oxygen
9. Two molecule that are very important to the Citric Acid Cycle
a. One molecule shuttles pyruvate into the cycle
b. The other one is required for the cycle to continue cellular respiration to completion
(i.e. complete oxidation of glucose)
10. The fate of all six carbon atoms in the original glucose molecule and the stage at which they
their oxidation was completed
11. Chemiosmosis and the number of ATP molecules produced by this process
12. Definition of oxidation & reduction in terms of electron transfer, the function of each substance
in the process & its effect on the other substance
13. The names of the two types of fermentation, the fermentation reaction(s) involved, and their
end product(s).

14. The only type of fermentation a human body can perform
15. The type/name of fermentation a yeast and some bacteria can perform
16. The products of the fermentation performed by the yeast and some bacteria
17. The main reactant(s) that are converted into chemical energy by photosynthesis through the use
of light energy.
18. The main plant pigment that absorbs solar energy
19. The product(s)/by-product(s) resulting from the effect of absorbed light energy on water
