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.
RESPIRATION AND FERMENTATION NOTES OBJECTIVE: TO DESCRIBE RESPIRATION AND FERMENTATION
Getting Energy from Food 1. How do we change food into usable energy? ANSWERS: Respiration and Fermentation
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
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.Reactants of respiration = oxygen and sugar 7.Products of respiration = carbon dioxide, water, ATP
Formula of Respiration GlucoseCarbon dioxide water Energy (ATP) Oxygen + + +
Respiration C 6 H 12 O 6 H2OH2O CO 2 O2O2 Carbon Dioxide glucose energy oxygen water
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
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
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
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
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
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.
WordDefinitionPicture Cellular Respiration Making energy (ATP) from sugar and oxygen
WordDefinitionPicture ATP Energy a cell can use!
WordDefinitionPicture Anaerobic respiration Making a little energy WITHOUT using oxygen - makes alcohol and lactic acid
WordDefinitionPicture Alcoholic fermentation Creates beer and bread, used by yeast glucose creates alcohol and carbon dioxide
WordDefinitionPicture Lactic Acid fermentation Creates wine, cheese, yogurt and pickles, used by yeast, bacteria and animals glucose creates lactic acid and ATP
WordDefinitionPicture Lactic acid Waste product of fermentation: makes muscles sore
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.
