3. I can explain how the citric acid (Krebs) cycle completes the energy yielding
oxidation of organic molecules.
a. I can describe where pyruvate is oxidized to acetyl CoA, what molecules
are produced, and how this process links glycolysis to the citric acid cycle.
b. I can list the products of the citric acid cycle and explain why it is called a
cycle.
c. I can identify the oxidizing agent of the citric acid cycle.

b. I can specifically describe where oxidative phosphorylation is occuring within
a cell.
c. I can explain where the energy for the active transport of hydrogen ions
comes from.
d. I can describe the energy transformations that occur from the time that NADH
is oxidized to ATP production.
e. I can state the number of ATP’s that are generated from the oxidation of 1
NADH and from 1 FADH2 via oxidative phosphorylation.
f. I can determine how 32 – 34 ATP’s are generated from oxidative
phosphorylation when beginning with the oxidation of 1 glucose molecule.
g. I can determine how many ATP’s would be generated by starting with any
molecule in cellular respiration, such as glucose, acetyl CoA etc…
h. I can explain why mitochondrial processes shut down in the absence of
oxygen.
5. I can explain how fermentation and anaerobic respiration allow cells to produce
ATP without the use of oxygen.
a. I can explain how glycolysis can continue in the absence of oxygen.
b. I can explain why pyruvate is a key juncture in cellular respiration.
c. I can distinguish between alcohol fermentation and lactic acid fermentation
and describe which organisms perform which reactions.
d. I can describe when and where fermentation is used in a cell.
6. I can show how glycolysis and the citric acid cycle connect to many other
metabolic pathways
a. I can describe how food molecules other than glucose can be oxidized to
make ATP’s.
b. I can explain how ATP production is regulated by the cell and describe the
role that allosteric enzymes such as phosphofructokinase plays in the process.
