Cellular Respiration is the complex process in which cells make ATP by breaking down organic compounds
3 Stages of Cellular Respiration
Glycolysis Krebs Cycle
Electron Transport
Chain
Glycolysis
•Organic compounds are converted into 3-Carbon molecules of PYRUVIC Acid, making ATP and NADH (an electron carrier molecule).•Cash vs Check• In Cytoplasm•Anaerobic process•Produces 2 ATPs of Energy

Pyruvic Acid
Aerobic Respiration
Anaerobic Respiration
If No Oxygen Present the Pyruvic Acid…•Anaerobic Process• Fermentation•Pyruvic acid is converted into NAD and NADH,
creating Lactic Acid (muscle soreness, cramps, fatigue)• Some plants convert Pyruvic acid into ethyl alcohol
If Oxygen is present the Pyruvic Acid
•Continues into the KREBS Cycle•Also called Citric Acid Cycle•Occurs in the Mitochondria
Krebs Cycle• Pyruvates with the help on an enzyme, Acetyl CoA, combine
with Oxaloacetic acid to make Citric Acid and also releases CO2.• Citric Acid then release more CO2 and a Hydrogen atom to
create a 5 Carbon molecule and NADH• The new 5 Carbon molecule release more CO2 and another
Hydrogen atom to make a 4 Carbon molecule and NADH• The 4 Carbon molecule releases another H and also FAD• The 4 Carbon molecule releases another H and forms
Oxaloacetic Acid and the Krebs cycle continues
Krebs Cycle
Electron Transport Chain (ETC)
•All of the FADs and NADHs created in Krebs Cycle give there electrons to the ETC •ETC ultimately produces ATP, up to 34 molecules!
Efficiency of Cellular Respiration
•1 Molecule of Glucose yields•34 molecules of ATP from ETC•2 molecules of ATP from Glycolysis•2 molecules of ATP from Krebs cycle
