1 Warm ups:During photosynthesis, plants use carbon dioxide and give off ________.C6H12O6 is the chemical formula for ____________________.Photosynthesis only occurs in cells that contain _______________________.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: RespirationandFermentation
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 Respiration4. Where does cellular respiration take place in eukaryotic cells?5 What must be present for cellular respiration to take place?4. Mitochondria5. OXYGEN AND SUGAR (food)
6 Reactants of respiration = oxygen and sugar Products of respiration = carbon dioxide, water, ATP
7 Formula of Respiration ++GlucoseCarbon dioxide+OxygenwaterEnergy (ATP)
8 Respiration ATP H2O CO2 O2 C6H12O6 water Carbon Dioxide oxygen glucose energy
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 oxygenANSWER:Without oxygen
10 Anaerobic Respiration 3. Where does anaerobic respiration take place?Does it create the same amount of ATP?There are 2 types of anaerobic respiration: what are they?ANSWER: in cytoplasmANSWER: no, less ATPANSWER:AlcoholicLactic acid
11 Alcoholic Fermentation 6. What type of organism’s do alcoholic fermentation?What is the formula?8. What do we use this process for?ANSWER: yeastANSWER:Beer andbreadGlucose alcohol + CO2 + ATP
12 Lactic Acid Fermentation 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, animalsANSWER:Wine, pickles, cheese, yogurtGlucose lactic acid + ATP
13 Lactic Acid Fermentation 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!
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 Word Definition Picture Making energy (ATP) from sugar and oxygenCellular Respiration
16 Word Definition Picture Energy a cell can use!ATP
17 Word Definition Picture Making a little energy WITHOUT using oxygen- makes alcohol and lactic acidAnaerobicrespiration
18 Word Definition Picture Creates beer and bread,used by yeastglucose creates alcohol and carbon dioxideAlcoholicfermentation
19 Word Definition Picture Creates wine, cheese, yogurt and pickles,used by yeast, bacteria and animalsglucose creates lactic acid and ATPLactic Acidfermentation
20 Word Definition Picture Waste product of fermentation: makes muscles soreLactic acid
21 Sum It Up Respiration and Fermentation both release energy form food. Respiration needs oxygen.Fermentation does not need oxygen. Fermentation makes VERY LITTLE ATP, so it’s not as efficient as respiration.
