Short Answer (6)
1. Identify two carbon based substances that are derived from the oxidation of glucose during glycolysis. (1)
2. During the Krebs cycle, two molecules are ‘temporarily’ reduced. They are only temporarily reduced
because they will eventually give up their electrons to the electron transport chain which hands off the
electron to the final electron acceptor in cellular respiration. Identify the two molecules that are
temporarily reduced in the Krebs cycle, and the final electron acceptor for cellular respiration. Why is this
final electron acceptor crucial to the entire process? (2)
3. Other than the end product, how does the process of ethanol and lactate fermentation differ? (1)
4. How is the formation of ATP in the electron transport chain of cellular respiration similar to that during
photosynthesis? What is this process called? Provide a diagram to illustrate. (2)
