4. Glycolysis It is an anaerobic process of splitting glucose forming two molecules of pyruvate It occurs in the cytoplasm (outside the mitochondria) 4 molecules of ATP are produced; net yield of 2 since it takes 2 ATP to begin glycolysis.

5. Krebs Cycle The series of reactions in which pyruvate (from glycolysis) is broken down into carbon dioxide is called the Krebs cycle. It occurs inside the mitochondria The yield from the Krebs cycle is six CO 2 molecules and two ATP

6. Electron Transport It is the final step in aerobic respiration It occurs in the mitochondria It produces the most ATP (24 ATP)

10. Alcohol Fermentation It occurs in yeast & some bacteria Pyruvate is converted to ethyl alcohol and carbon dioxide

11. Lactic Acid Fermentation It occurs in skeletal muscles Pyruvate is converted to lactic acid when the body cannot supply enough oxygen Why muscles become sore and fatigued It is produced by microorganisms to make cheese, yogurt, and sour cream
