1. The steps of Cellular Respiration
Step 1: Glycolysis Glyco = glucose Lysis = to split Glucose is split in two! Reactant: glucose Products: 2 ATP and 2 pyruvate (half of glucose) WHERE? In the cytoplasm

2. Glycolysis

3. The steps of Cellular Respiration
Step 2: Kreb’s Cycle
Step 3: Electron Transport Chain (ETC) Reactants (of steps 2 & 3): Oxygen and pyruvate
Products: Carbon dioxide, water, and 36 ATP
WHERE? In the mitochondria
Cristae

4. Krebs Cycle

5. Electron Transport Chain

7. Review What are the products of cellular respiration?

Where is the energy in ATP stored?
Why do we need to eat food and breathe oxygen?
