Unformatted text preview: ATP can be made in glycolysis. Electrons from NADH are added to pyruvate ( reduction ) to produce alcohol (plants, yeast) or lactate (animals, bacteria) Aerobic Respiration Aerobic respiration occurs when oxygen is available. pyruvate CO 2 + H 2 O It occurs in the mitochondrion . NAD + and FAD carry electrons to the electron transport system. In the electron transport system, NADH and FADH 2 are used to produce ATP as electrons are passed from one carrier to another. Eventually the electrons combine with hydrogen ions and oxygen ( reduction ) to form water . Click the icon (left) to see an enlarged, color version of the diagram above....
