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

2. 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!

3. 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)

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

5. 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!

6. 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?
