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

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.
