Solution Steps

Step 1: Identify the stages of cellular respiration

The figure shows the four stages of cellular respiration: Glycolysis, Pyruvate oxidation, Citric acid cycle, and Oxidative phosphorylation.

Step 2: Determine the molecules produced in each stage

Using the answer bank, identify the molecules produced in each stage of cellular respiration.

Step 3: Label the empty boxes with the correct molecules
  • Stage 1: Glycolysis produces Pyruvate and ATP.
  • Stage 2: Pyruvate oxidation produces Acetyl-CoA and CO₂.
  • Stage 3: Citric acid cycle produces CO₂, ATP, NADH, and FADH₂.
  • Stage 4: Oxidative phosphorylation produces ATP and H₂O.

Final Answer

  • Stage 1: Glycolysis: Pyruvate, ATP
  • Stage 2: Pyruvate oxidation: Acetyl-CoA, CO₂
  • Stage 3: Citric acid cycle: CO₂, ATP, NADH, FADH₂
  • Stage 4: Oxidative phosphorylation: ATP, H₂O
