REDOX AND CELLULAR RESPIRATION REVIEW
- Write a balanced equation for cellular respiration. What is oxidized? What is
reduced? What is the oxidizing agent? What is the reducing agent?
- Summarize the endosymbiotic theory and the evidence for it.
- What is needed for glycolysis? What are the products?
- What evidence is there that indicates that glycolysis is a very old process?
- What is needed for pyruvate oxidation? What are the products?
- What is needed for the Krebs cycle? What are the products?
- What are the differences between substrate-level phosphorylation and oxidative
phosphorylation?
- What is the role of NADH in cellular respiration?
- What is the role of FADH2 in cellular respiration?
- What is the role of oxygen in cellular respiration?
- Why do cells undergo anaerobic respiration?
- What are two anaerobic options for organisms? What are their products?
- Name the members of the ETC.
- Explain the process of chemiosmosis in the mitochondrion. Draw a picture.
- Explain why the architecture of the mitochondrion is suited for ATP production.
- Why are there two (theoretical and actual) conversion rates for NADH and FADH2?
- Theoretically, how many ATP are created from one glucose molecule?
- Actually, how many ATP are created from one glucose molecule?
- Is glucose the only useful macromolecule used in cellular respiration? Explain.
- One glucose contains 686 kcal of energy. One ATP is 7.3 kcal. Overall efficiency of
cellular respiration? Efficiency of glycolysis? pyruvate oxidation? Krebs cycle?
