- What is an oxidation/reduction reaction and how do these
result in the release of energy? In the overall summarizing
of cellular respiration (C6H12O6 + O2
--> CO2 + H2O), what is being oxidized?
What is being reduced?
- Understand the function of electron carrier molecules (NAD+,
and FAD) in cellular respiration. How are they reduced to NADH
- Where in the cell/mitochondria (matrix, inner mitochondrial
intermembrane space) do each of the three stages of cellular
- What do we mean when we say that energy is harnessed during glycolysis
through substrate level phosphorylation of ADP and oxidation of
glucose to pyruvate. What happens to
molecules if oxygen is present (aerobic metabolism)? What
happens to them if it is not present (anaerobic metabolism)?
- Describe in general the two ways energy is harnessed during the Krebs
cycle. How are ATP, NADH, FADH2 produced during
Krebs cycle? Why do we refer to the Krebs cycle as the main
oxidative pathway of cellular respiration?
- Once the NADHs and FADH2s of glycolysis and the Krebs
are produced, what is their function in the cell?
- Describe the Chemiosmotic Model of ATP production during
Transport Chains of cellular respiration with respect to the
Describe the anaerobic pathway know as fermentation.
that muscle cells are facultative anaerobes (they can switch between
cellular respiration and fermentation) and why.
How are other organic molecules like fats and proteins

- What is a proton motive force, and how is it used to
- What is the role of ATP Synthase?
