The document discusses cellular respiration, which is the process cells use to convert glucose into energy in the form of ATP. It occurs in three main stages: glycolysis, the Krebs cycle in the mitochondria, and the electron transport chain in the mitochondria. Glycolysis produces a small amount of ATP, while the electron transport chain produces the majority of ATP. Cellular respiration requires oxygen and glucose to produce water, carbon dioxide, and ATP as waste products. It is the reverse of photosynthesis.
