What Are the Three Main Stages of Aerobic Cellular Respiration

Generates most of the ATP formed by cell respiration

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

Begins the oxidation of glucose

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

occurs outside the mitochondrion

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

Produces four ATP per glucose but two ATPs per glucose are used to get it started

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

Oxidizes NADH and FADH2, producing NAD⁺ and FAD⁺²

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

Carried out by enzymes only in the matrix of the mitochondrion.

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

Here electrons and hydrogen combine with O2 for form H2O

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

Where ATP synthase makes ATP

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

Reduces NAD⁺ and FAD⁺² producing NADH and FADH₂

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain

Produces 28 molecules of ATP for every glucose consumed

• Glycolysis

• Krebs Cycle (Citric Acid Cycle)

• Electron Transport Chain
