Diagram
Draw and label the process of aerobic cellular respiration in the space below. Include the following structures and
processes in your diagram: mitochondria, glycolysis, Krebs cycle, electron transport chain, reactants, products, ATP,
pyruvate (pyruvic acid).
Glycolysis
1. Briefly summarize the events (reactions) that occur during glycolysis.
2. Where does glycolysis occur in the cell?
3. What is formed during glycolysis?
1
Krebs Cycle
4. Briefly summarize the events (reactions) that occur during the Krebs cycle.
5. Where does the Krebs cycle occur in the cell?
Electron Transport Chain and ATP
6. Briefly summarize the events (reactions) that occur during the electron transport chain.
7. Where does the electron transport chain occur in the cell?
Energy Totals
8. How much chemical energy (in the form of ATP molecules) is produced by the complete breakdown of 1 glucose
molecule during glycolysis and aerobic respiration?
9. A unit (mole) of glucose molecules contains 686 kcal. A unit of ATP molecules stores 7.5 kcal. Considering
how many units of ATP are produced per unit of glucose, how efficient is the burning of glucose fuel in cellular
respiration? Show your work.
Is this energy transformation more or less efficient than the 25% efficiency of burning of gasoline fuel in an
automobile?
Relationships
10. How are cellular respiration and breathing (respiration) related?
11. Analyze the figure at the right and discuss how
cellular respiration and photosynthesis are related.
