Cellular Respiration

Published on 07/01/2011

Activity Overview

In this lesson, students will use different simulations to explore three pathways involved in cellular respiration.


  • Students will understand that cells utilize chemical energy from glucose by breaking chemical bonds.
  • Students will be familiar with several important pioneers in metabolic science.
  • Students will know that cells use enzymatic pathways to catalyze glycolysis, the Krebs cycle (or Citric Acid Cycle) and the electron transport chain.


  • Glycolysis
  • Krebs cycle
  • Electron Transport Chain
  • NADH
  • ATP
  • Glucose
  • Metabolize
  • Pyruvic acid
  • FADH2

About the Lesson

Using several simulations, students will explore three pathways involved in cellular respiration. Assessments are embedded in the activity to engage discussion and gauge learning.
As a result, students will:

  • Learn the basic functions of glycolysis, the Krebs cycle and the electron transport chain as metabolic pathways that extract energy from food.
  • Learn to recognize the relative energetic content of the energy-containing molecules glucose, NADH, FADH2 and ATP.
