Outcome: Cellular Respiration

Identify the reactants and products of cellular respiration and where these reactions occur in a cell.

Now that we’ve learned how autotrophs like plants get their energy, let’s take a look at how heterotrophs—which includes humans!—get their energy.

What You’ll Learn to Do

  • Describe the process of glycolysis and identify its reactants and products.
  • Describe the process of pyruvate oxidation and identify its reactants and products.
  • Describe the process of the citric acid cycle (Krebs cycle) and identify its reactants and products.
  • Describe the respiratory chain (electron transport chain) and its role in cellular respiration.
