KEY CONCEPT Cellular respiration is an aerobic process which convert glucose to energy in animals

Equation for cellular respiration KNOW cellular respiration equation C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy KNOW how to write equation in words glucose + oxygen → carbon dioxide + water + energy This is how we get energy to do anything everything!

Step 1: Glycolysis – Breakdown of glucose Energy (ATP) is needed to break down glucose *This will eventually lead to more ATP being made Two ATP molecules are used to split glucose Four ATP molecules are produced NADH produced 2 Pyruvates produced (3 carbon molecules)

Step 2: Krebs cycle   The 2 three carbon pyruvates are broken down to produce more NADH and FADH2

Step 3: electron transport chain The Hydrogen's on the NADH and FADH2 carry energy into the cell via gradient Water released as waste It is the cell in our body that needs energy!

So we said glucose creates 35 ATP/molecule? The breakdown of one glucose molecule produces 38 molecules of ATP. Why did we sat 1 glucose molecule makes 36 total ATP?
