Catabolism, catabolic pathway

• Catabolic pathways are metabolic pathways that
  release stored energy by breaking down complex
  molecules.
• Fermentation and cellular respiration are
  examples of catabolic pathways.

3
Cellular respiration

• Cellular respiration occurs in mitochondria.
  Oxygen is consumed as a reactant together with
  the organic fuel.
• Although carbohydrates, fats, and proteins are
  all fuel, it is traditional to learn the steps of
  respiration by tracking the degradation of
  glucose.

4
ATP, Adenosine TriPhosphate

• The close packing of the three negatively charged
  phosphate groups of ATP become an unstable,
  energy-storing arrangement.
