1 Section 4-4 & 4-6 “Cellular Respiration / Fermentation” Write everything that is BLACK
2 4.4 KEY CONCEPT The overall process of cellular respiration converts sugar into ATP using oxygen
3 Cellular respiration makes ATP by breaking down sugars. Cellular respiration is aerobic (requires oxygen)It happens in the mitochondriamitochondrionanimal cell
4 Glycolysis must take place first. anaerobic process (does not require oxygen)takes place in cytoplasmsplits glucose into two three-carbon moleculesproduces two ATP molecules
5 Cellular respiration is like a mirror image of photosynthesis. The Krebs cycle transfers energy to an electron transport chain.takes place in mitochondrial matrixbreaks down three-carbon molecules from glycolysisKrebs Cycle6H O26CO6Omitochondrionmatrix (area enclosedby inner membrane)inner membraneATPenergyenergy from glycolysis143andmakes a small amount of ATPreleases carbon dioxidetransfers energy-carrying molecules

7 The equation for cellular respiration: C6H12O6 + 6O2 6CO2 + 6H2O The reactants in photosynthesis are the same as the products of cellular respiration.
8 4.6 KEY CONCEPT Fermentation allows the production of a small amount of ATP without oxygen.
9 Fermentation allows glycolysis to continue making ATP when oxygen is unavailable. Fermentation is an anaerobic processoccurs when oxygen is not available for cellular respirationdoes not produce ATP
10 Lactic acid fermentation occurs in muscle cells glycolysis splits glucose into two pyruvate moleculespyruvate and NADH enter fermentationenergy from NADH converts pyruvate into lactic acidNADH is changed back into NAD+
11 Alcoholic fermentation is similar to lactic acid fermentation Fermentation is used in food production.yogurtcheesebread
