Chapter 9 – Cellular Respiration

·         What reactions are exergonic?

·         What reactions are oxidation-reduction reactions?

·         Of the substances involved (glucose, oxygen, carbon dioxide, and water) which are oxidized and which are reduced during cellular respiration?

·         What occurs during an oxidation-reduction reaction?

·         Which is the oxidized form of the electron carrier: NAD+ OR NADH?

·         Is the oxidized or reduced form made during glycolysis and the citric acid cycle?

·         Is the oxidized or reduced form made during oxidative phosphorylation?

·         Which of these two substances is carrying energized electrons to the electron transport chain: NADH or NAD+?

·         Same question as above for: FADH or FADH2

·         Cellular respiration requires three main processes. What are they called and in what part(s) of a cell do each occur?

·         What is the difference between substrate-level phosphorylation and oxidative phosphorylation?

·         What molecules enter and exit glycolysis, citric acid cycle, and oxidative phosphorylation?

·         What is the purpose of the electron transport chain?

·         How does the purpose of oxygen relate to the purpose of the electron transport chain?

·         What is the role of H in the ETC?

·         Which of the three processes does fermentation use? (Glycolysis, Citric acid cycle, or Ox-Phos?)

·         What is the purpose of the reduction of pyruvate to lactate or alcohol?
