Cellular Respiration
  Phase 1: Glycolysis (occurs in the cytoplasm)
    Sub-phase 1: Phosphorylation of glucose
    Sub-phase 2: Conversion of glucose to fructose 1,6-bisphosphate
    Sub-phase 3: Cleavage of fructose 1,6-bisphosphate into two three-carbon molecules
  Phase 2: Preparatory (or Link) Stage (occurs in the mitochondria)
    Sub-phase 1: Conversion of the three-carbon molecules into high-energy intermediates
    Sub-phase 2: Transport of the high-energy intermediates into the mitochondria
  Phase 3: Krebs Cycle (or Citric Acid Cycle) (occurs in the mitochondria)
    Sub-phase 1: Oxidation of the high-energy intermediates
    Sub-phase 2: Release of carbon dioxide
    Sub-phase 3: Production of ATP, NADH, and FADH2
  Phase 4: Electron Transport Chain (occurs in the inner membrane of mitochondria)
    Sub-phase 1: Oxidation of NADH and FADH2
    Sub-phase 2: Transfer of electrons from one molecule to another
    Sub-phase 3: Generation of a proton gradient
    Sub-phase 4: Conversion of the proton gradient into ATP
