1Warm 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.
2RESPIRATION AND FERMENTATION NOTES OBJECTIVE: TO DESCRIBE RESPIRATION AND FERMENTATION
3Getting Energy from Food 1. How do we change food into usable energy?ANSWERS: RespirationandFermentation
4Cellular 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
5Cellular 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)
6Reactants of respiration = oxygen and sugar Products of respiration = carbon dioxide, water, ATP
7Formula of Respiration ++GlucoseCarbon dioxide+OxygenwaterEnergy (ATP)
8Respiration ATP H2O CO2 O2 C6H12O6 water Carbon Dioxide oxygen glucose energy
9Anaerobic 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
10Anaerobic 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
11Alcoholic 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
12Lactic 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
13Lactic 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!
14Why 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.
15Word Definition Picture Making energy (ATP) from sugar and oxygenCellular Respiration
16Word Definition Picture Energy a cell can use!ATP
17Word Definition Picture Making a little energy WITHOUT using oxygen- makes alcohol and lactic acidAnaerobicrespiration
18Word Definition Picture Creates beer and bread,used by yeastglucose creates alcohol and carbon dioxideAlcoholicfermentation
19Word Definition Picture Creates wine, cheese, yogurt and pickles,used by yeast, bacteria and animalsglucose creates lactic acid and ATPLactic Acidfermentation
20Word Definition Picture Waste product of fermentation: makes muscles soreLactic acid
21Sum 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.
