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
Glycolysis
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
Krebs Cycle
Electron Transport Chain
Review What are the products of cellular respiration? What is ATP used for? Where is the energy in ATP stored? Why do we need to eat food and breathe oxygen?
