1 Warm ups: 1.During photosynthesis, plants use carbon dioxide and give off ________. 2.C 6 H 12 O 6 is the chemical formula for ____________________. 3.Photosynthesis only occurs in cells that contain _______________________. 4.During photosynthesis, plants remove ___________________ from the air.

2 RESPIRATION AND FERMENTATION NOTES OBJECTIVE: TO DESCRIBE RESPIRATION AND FERMENTATION

3 Getting Energy from Food 1. How do we change food into usable energy? ANSWERS: Respiration and Fermentation

4 Cellular Respiration 2. What happens during cellular respiration? 3. How is the energy is stored? ANSWER: Food is broken down and energy is released. ANSWER: ATP molecules

5 Cellular Respiration 4. Where does cellular respiration take place in eukaryotic cells? 5 What must be present for cellular respiration to take place? 4. Mitochondria 5. OXYGEN AND SUGAR (food)

6 6.Reactants of respiration = oxygen and sugar 7.Products of respiration = carbon dioxide, water, ATP

7 Formula of Respiration GlucoseCarbon dioxide water Energy (ATP) Oxygen + + +

8 Respiration C 6 H 12 O 6 H2OH2O CO 2 O2O2 Carbon Dioxide glucose energy oxygen water

9 Anaerobic Respiration 1.What is anaerobic respiration? 2. What does “anaerobic” mean? ANSWER: When energy still needs to be made, but there is no oxygen ANSWER: Without oxygen

10 3. Where does anaerobic respiration take place? 4.Does it create the same amount of ATP? 5.There are 2 types of anaerobic respiration: what are they? ANSWER: in cytoplasm ANSWER: no, less ATP ANSWER: 1. Alcoholic 2. Lactic acid Anaerobic Respiration

11 6. What type of organism’s do alcoholic fermentation? 7.What is the formula? 8. What do we use this process for? ANSWER: yeast ANSWER: 1. Beer and bread Alcoholic Fermentation Glucosealcohol + CO2 + ATP

12 9. What type of organism’s do lactic acid fermentation? 10. What is the formula? 11. What do we use this process for? ANSWER: bacteria, yeast, animals ANSWER: 1. Wine, pickles, cheese, yogurt Lactic Acid Fermentation Glucoselactic acid + ATP

13 12. Did you ever have sore muscles? 13. Why do you get sore muscles? ANSWER: This happens when your cells don’t have enough oxygen present for cellular respiration then fermentation takes place. ANSWER: lactic acid gives you sore muscles! Lactic Acid Fermentation

14 Why would fermentation be helpful? If your body couldn’t get oxygen fast enough, it can still make a little energy. If a bacteria is living in an environment with no oxygen, it can still survive.

15 WordDefinitionPicture Cellular Respiration Making energy (ATP) from sugar and oxygen

16 WordDefinitionPicture ATP Energy a cell can use!

17 WordDefinitionPicture Anaerobic respiration Making a little energy WITHOUT using oxygen - makes alcohol and lactic acid

18 WordDefinitionPicture Alcoholic fermentation Creates beer and bread, used by yeast glucose creates alcohol and carbon dioxide

19 WordDefinitionPicture Lactic Acid fermentation Creates wine, cheese, yogurt and pickles, used by yeast, bacteria and animals glucose creates lactic acid and ATP

20 WordDefinitionPicture Lactic acid Waste product of fermentation: makes muscles sore

21 Sum It Up 1.Respiration and Fermentation both release energy form food. 2.Respiration needs oxygen. 3.Fermentation does not need oxygen. Fermentation makes VERY LITTLE ATP, so it’s not as efficient as respiration.
