Overall Learning Goal – Explain how glucose is used to generate ATP in eukayryotes.
Learning Objective: Metabolism Students will be able to:
  1. Define the inputs and outputs of eukaryotic cellular respiration including the location of each reaction..
  2. Explain how glucose is used to generate ATP and why electron carriers are important to this process.
Formative Assessment:
Work in groups to complete the flow chart diagramming four processes of cellular respiration. Indicate the inputs and outputs of each step. Label each box with the name of the process represented.

Answer the clicker questions.

  1. Which arrow in the figure represent NADH?
  2. Which arrow in the figure represent Acetyl CoA?
  3. Which arrow in the figure represents O2?




Summative Assessment:
Cyanide (CN) blocks the flow of electrons through the electron transport chain.
A new organism with unusual organelles has been discovered. In order to determine the possible functions of these unusual organelles, cells were fractionated, and the different fractions incubated for 30 sec. with the following additions. The fractions were then assayed for ATP production.
The results are shown in the table below.

  1. Based on the table above, in which fraction does oxidative phosphorylation occur ?
    1. Fraction 1
    2. Fraction 2
    3. Fraction 3
    4. Fraction 4
    5. Which cellular organelles are present in the fraction that supports oxidative phosphorylation?
      1. Golgi
      2. Cytoplasm
      3. Mitochondria
      4. Mitochondria and cytoplasm
Cyanide blocks the flow of electrons through the electron transport chain. Based on this information and the data in the table above, indicate which of the following statements are true or false.
T/F Fraction 2 must contain components of the electron transport chain.
T/F Substrate level phosphorylation occurs in fraction 4.
T/F Cyanide has no effect on ATP produced in the presence of pyruvate.
