1 Section 4-4 & 4-6 Cellular Respiration / Fermentation Section 4-4 & 4-6 Cellular Respiration / Fermentation Write everything that is BLACK

2 4.4 Cellular Respiration / 4.6 Fermentation 4.4 KEY CONCEPT The overall process of cellular respiration converts sugar into ATP using oxygen

3 4.4 Cellular Respiration / 4.6 Fermentation mitochondrion animal cell Cellular respiration makes ATP by breaking down sugars. Cellular respiration is aerobic (requires oxygen)Cellular respiration is aerobic (requires oxygen) It happens in the mitochondriaIt happens in the mitochondria

4 4.4 Cellular Respiration / 4.6 Fermentation Glycolysis must take place first.Glycolysis must take place first. –anaerobic process (does not require oxygen) –takes place in cytoplasm –splits glucose into two three-carbon molecules –produces two ATP molecules

5 4.4 Cellular Respiration / 4.6 Fermentation Cellular respiration is like a mirror image of photosynthesis. The Krebs cycle transfers energy to an electron transport chain.The Krebs cycle transfers energy to an electron transport chain. –takes place in mitochondrial matrix –breaks down three-carbon molecules from glycolysis –makes a small amount of ATP –releases carbon dioxide –transfers energy-carrying molecules 6H O 2 6CO 2 6O 2 mitochondrion matrix (area enclosed by inner membrane) inner membrane ATP energy energy from glycolysis and Krebs Cycle

6 4.4 Cellular Respiration / 4.6 Fermentation 6H O 2 6CO 2 6O 2 mitochondrion matrix (area enclosed by inner membrane) inner membrane ATP energy energy from glycolysis and The electron transport chain produces a large amount of ATP.The electron transport chain produces a large amount of ATP. –takes place in inner membrane –energy transferred to electron transport chain –oxygen enters process –ATP produced –water released as a waste product Electron Transport

7 4.4 Cellular Respiration / 4.6 Fermentation The equation for cellular respiration:The equation for cellular respiration: C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O The reactants in photosynthesis are the same as the products of cellular respiration.The reactants in photosynthesis are the same as the products of cellular respiration.

8 4.4 Cellular Respiration / 4.6 Fermentation 4.6 KEY CONCEPT Fermentation allows the production of a small amount of ATP without oxygen.

9 4.4 Cellular Respiration / 4.6 Fermentation Fermentation is an anaerobic processFermentation is an anaerobic process –occurs when oxygen is not available for cellular respiration –does not produce ATP Fermentation allows glycolysis to continue making ATP when oxygen is unavailable.Fermentation allows glycolysis to continue making ATP when oxygen is unavailable.

10 4.4 Cellular Respiration / 4.6 Fermentation Lactic acid fermentation occurs in muscle cellsLactic acid fermentation occurs in muscle cells –glycolysis splits glucose into two pyruvate molecules –pyruvate and NADH enter fermentation –energy from NADH converts pyruvate into lactic acid –NADH is changed back into NAD +

11 4.4 Cellular Respiration / 4.6 Fermentation Alcoholic fermentation is similar to lactic acid fermentationAlcoholic fermentation is similar to lactic acid fermentation Fermentation is used in food production.Fermentation is used in food production. –yogurt –cheese –bread

12 4.4 Cellular Respiration / 4.6 Fermentation Pages 5, 6, & 7 1.Page 5 Title this page Cellular Respiration -What is the function of cellular respiration? -What is the difference between aerobic and anaerobic? -Which of the above does cellular respiration require? -What does the kreb cycle do? -What does the electron transport chain do? 2. Page 6 Title this page COMPARING PROCESSES -On page 115 draw figure 4.12 and under each drawing write the equation that fits the drawing

13 4.4 Cellular Respiration / 4.6 Fermentation 3.Page 7 Title this page Fermentation -Write the key concept for fermentation Which type of process is fermentation? What does that term mean? -Describe the difference between Lactic acid fermentation and alcoholic fermentation. -Give 3 examples of alcoholic fermentation
