5. Homework Quiz: Write the answers down that you have on your homework for the specific questions. When you finish please turn it into the tray. If you do not have some answers on homework you CANNOT answer on quiz!!

6. I. Energy and living organisms A. Photosynthesis- light energy (sunlight) is converted to chemical energy (glucose) 1. Autotrophs- use sunlight to make own energy-food 2. Heterotrophs- organisms that must get energy from food instead of directly from sunlight (must eat)

7. B. Living things store energy in compounds such asATPandADP 1. ATP consists of: a. adenine b. ribose (a 5-carbon sugar) c. 3 phosphate groups Draw an ATP molecule on your notesheet!

8. 2. Energy stored in bonds between phosphate groups, break bonds release energy * The phosphate “tails” are unstable due to their negative charges * Negative phosphate groups want to repel each other a. ATP breaks off a P, releases energy, becomes ADP 3. ATP – P -----→ ADP (adenosine diphosphate)

9. Released ENERGY After the ATP loses its phosphate group, its becomes ADP, then it gets a new phosphate group and is ATP again! a. ADP then gets another P added to it (recharged) and is ready to be used again Energy Adenosine Diphosphate Adenosine Triphosphate Fullycharged battery Partiallycharged battery

10. C. How ATP is used 1. During Active transport 2. move organelles inside the cell along microtubules (like a train track) 3. Storing and transferring small amounts of energy a. One molecule of glucose can store 90 X the amount of energy of one ATP **energy currency example**

24. II.Breaking down glucose A. Glycolysis- in cytoplasm 1. One molecule of glucose is used and 2 ATP are created 2. One glucose goes in a 2 pyruvic acids are made 3. Small yield but happens so fast, thousands of ATP per ms-Can happen w/o oxygen 4. NAD+ →NADH , carries high energy electrons IN OUT 1 glucose 2 pyruvic acid 2 ATP (investment) 4 ATP (net gain 2 ATP) NAD+ NADH

25. B. Kreb’s Cycle-in mitochondria 1. Aerobic-need oxygen to do 2. Makes CO2 , and ATP 3. electron carriers- FADH and NADH, made to use during ETC INOUT FAD FADH NAD NADH CO2 2 Pyruvic acid ATP (now the energy source) 4. pyruvic acid is broken apart and energy is used to make ATP, make and release CO2 and transfer high e electrons to FAD and NAD

27. C. Electron Transport Chain -uses high energy electrons from Krebs cycle to make ATP out of ADP 1. Aerobic-takes in O2 and releases water 2. Lots of ATP made by ATP synthase- attaches a phosphate group to ADP using hydrogen ions H+ 3. in mitochondria INOUT FADH FAD NADH NAD O2 H2O ADP lots of ATP

31. D. Totals: With oxygen present Cellular Respiration forms about 38 molecules of ATP per molecule of glucose 1. 2- Glycolysis 2- Krebs 34-ETC

39. Flowchart Section 9-2 Cellular Respiration Glucose(C6H1206) + Oxygen(02) Glycolysis ElectronTransportChain Carbon Dioxide (CO2) + Water (H2O) • What process is missing from this flow chart? • What is the main point of cellular respiration? Go to Section:

40. 3. What process is this picture showing? 4. Glucose is being split into 2 what? 5. 2 ATP are put into this reaction and how many are produced? Glucose 2 Pyruvic acid To the electron transport chain

41. NADH FADH2 6. Both of these molecules function as what? 7. What organelle is this a picture of? 8. What happens in this organelle?

42. Glycolysis -2 pyruvic acids -2 ATP -NADH Krebs -few ATP -FADH, NADH -CO2 ETC - lots of ATP - Take in O2, release water

43. TURN IN YOUR PICTURES!! Turn in your quiz to basket when you are done. Then grab the reading assignment from the side lab table and work on it!

44. III. Breaking down glucose in the absence of Oxygen A. Fermentation – releases energy from food molecules in the absence of oxygen 1. Anaerobic- not using oxygen 2. Cells convert NADH back into NAD+ 3. Glycolysis repeats itself (a lot)

45. B. 2 types of fermentation: 1. Lactic Acid fermentation- a. Pyruvic acid that accumulates as a result of glycolysis is converted to lactic acid b. Produced by muscles during exercise when the body cannot supply enough oxygen 1.) Build up of lactic acid causes painful burning in muscles

46. 2. Alcoholic- Yeasts use; produce small amount of ATP pyruvic acid + NADH→ alcohol +CO2+ NAD+ a. Yeast in dough runs out of oxygen, does fermentation, CO2 causes bubbles in bread

47. History: Louis Pasteur studied fermentation to help the French wine industry. He discovered “the Pasteur Effect” – When yeast and grape juice are sealed into a fermentation vessel, the yeast grows until all the oxygen is used up. At this point the yeast switches to fermentation and alcohol is produced. Sugar is used up very quickly by the yeast during fermentation since little energy can be released from each glucose molecule without O2 (2ATP).

48. IV. Energy and Exercise • To obtain energy the body uses energy already in muscles, ATP made by lactic acid fermentation, and ATP made by cellular respiration B. Quick Energy- lots of energy fast. Your body will first use the energy stored in muscles, but then have to switch to lactic acid fermentation (90 seconds or less) 1. Oxygen Debt- the only way to get rid of lactic acid is to get extra oxygen into your body-deep breaths C. Long term energy- Over 90 seconds requires cellular respiration to generate a continuous supply of ATP. 1. For 15-20 minutes your body breaks down glycogen (carbohydrates), after this your body starts to breakdown fats

49. Biology: Grab the lab sheet from the front of the room… Read through it and answer the PRE-LAB Questions! Today 11/27/2013: Investigate Muscle Fatigue Analyze Data Fermentation Quiz Next Week Wednesday!! NO Homework!! Have a safe and fun Thanksgiving Weekend!!

50. Muscle Fatigue: Muscle cells often need a very large supply of ATP for rapid bursts of activity. For short, quick bursts of energy, the body uses ATP already in muscles as well as ATP made by lactic acid fermentation When lactic acid fermentation happens the lactic acid builds up in muscle cells and causes painful burning.
