Cellular Respiration -Cellular respiration is process in which cells convert the energy in foods into ATP, which cells can use as energy C6H12O2 + 6 O2 6 H2O + 6 CO2 -this is the reverse equation of photosynthesis -much of cellular respiration occurs in the mitochondria

Cellular Respiration -cellular respiration begins outside the mitochondria in a process known as glycolysis -glycolysis is the process of turning glucose into pyruvic acid which becomes pyruvate, which is used by the mitochondria to produce ATP -NADH and tiny amount of ATP is generated by this process in itself

Cellular Respiration -much of the ATP that comes from cellular respiration comes from the mitochondria through the Krebs cycle and electron transport chain

Cellular Respiration -the pyruvate is transformed into Acetyl CoA before going through the Krebs cycle -as pyruvate is transformed, it produces NADH -in the Krebs cycle, the Acetyl CoA is broken down into carbon dioxide molecules and ATP, NADH, and FADH2 is produced
