  1. 1Forms Of EnergyChemical
    Mechanical
    Heat
  2. 2Is exercise required to convert chemical energy to mechanical?yes
  3. 3How long do we need to start generating ATP?Right away
  4. 4Sources of ATPPhosphocreatine System
    Aerobic System
    Lactic Acid System
  5. 5Where is Glycogen stored?Muscle and Liver
  6. 6Where is glucose storedBlood stream
  7. 7Where does the citric acid cycle take place?Mitochondria
  8. 8Where does the electron transport chain take place?Mitochondria
  9. 9Glycolytic Pathwaystarts with 1 glucose
    ends with 2 pyruvic acids
  10. 10Does pyruvic acid enter the citric acid cycle?No
  11. 11What enters into the citric acid cycle?Acetyl Co-Enzyme A
  12. 12Citric Acid CyclePyruvic acid turns into acetly co-enzyme a
    8 pairs of carrier molecules taken to Electron transport chain
  13. 13What does the citric acid cycle end with?4 CO2 and 2 AtP
  14. 14How many molecules of glucose does it take for 2 cycles of Citric Acid Cycle1
  15. 15Electron Transport ChainInvolves electron carriers brought from Citric acid cycle
  16. 16What system creates the most ATPElectron Transport System
    34
  17. 17What is the end result of the Electron Transport SystemWater
  18. 18Fatsonly aerobically
  19. 19where are fats stored?adipose tissue
  20. 20What is Beta-OxidationBreak down of fats in order to enter Citric Acid Cycle
    Breaks down fatty acids and ends with Acetyl coenzyme A
  21. 21What is Oxygen DeficitTime period during exercise in which the level of oxygen consumption is below that necessary to supply all the ATP required
  22. 22What is Oxygen Deficit compared to?Spending money we do not have
  23. 23What system do you use when exercising less than 30 secondsPhosphocreatine system
    increasing lactic acid system and aerobic system
  24. 24What system do you use when exercising for 30 seconds - 2 minutes?Mainly lactic acid system
    early phosphocreatine system
    increasing aerobic system
  25. 25Source of energy when exercising past 2 minutes?Aerobic System
    if increasing exercise it may require lactic acid system
  26. 26After work what do carbs replenish?Muscle glycogen (storage form of carbohydrates)
  27. 27What does continuous exercise require?Higher amount of carbohydrates
  28. 28What do you need to replenish after exercise?ATP
    Phosphocreatine
    Muscle glycogen
    Liver glycogen (sometimes)
  29. 29Oxygen DebtThe amount of oxygen consumed during recovery from exercise, above that ordinarily consumed at rest in the same period
  30. 30Alactacid(FAST)
    Rapid recovery phase
    Replenishment of ATP and Phosphocreatine
  31. 31Lactacid(SLOW)
    Slow recovery phase
    removing lactic acid
    Most is CO2 and water
  32. 32Fates of Lactic AcidOxidation to CO2 and water
    Conversion to glucose and/or glycogen
    Conversion to protein
    Excretion in urine and sweat
  33. 33Pulmonary VentilationMinute Ventilation
    Tidal Volume
    Frequency
  34. 34Minute VentilationVolume of air we take in or take out each minute
  35. 35Tidal VolumeVolume of air we take in or take out with each breath
  36. 36FrequencyNumber of breaths we make each minute
  37. 37Do larger people have a larger minute ventilation at rest and during exercise?yes
  38. 38Do trained and untrained individuals ave the same ventilation at rest?Yes
  39. 39When breathing rate increases are you consuming more oxygen?no
  40. 40VO2Oxygen Consumption
  41. 41VCO2CO2 production
  42. 42Strength of carbonic acidweak
  43. 43During Carbon Dioxide Transport what does CO2 become?Bicarbonate Ions
  44. 44Carbon Dioxide TransportCO2 moves into red blood cells where it becomes bicarbonate ion, then moves into plasma because chloride enters the red blood cell
  45. 45What is chloride shift?Chloride ions move into red blood cells so hydrogen can move out and allow bicarbonate ions to leave red blood cells
  46. 46High PHBasic
  47. 47Low PHAcidic
  48. 48Oxyhemoglobin Dissociation CurvePercent saturation of hemoglobin with oxygen as a function of partial pressure of oxygen
  49. 49Does the Oxyhemoglobin dissociation curve shift left or right?Right
  50. 504 factors affecting oxyhemoglobin curve during exerciseincreased temp of blood
    decease of PH
    Increase partial pressure of C)2
    Increase of 2,3 DPG
  51. 51When your temperature rises (exercise) what do you release more ofoxygen to the muscle
  52. 52What is oxyhemoglobin?Oxygen and Hemoglobin
    ! globin carries CO2 and 4 Heme which carry O2
  53. 53What does iron love in Oxygen Transport?Oxygen
  54. 54What if we didn't have red blood cells?the amount of oxygen we would have would allow us to live for 4 seconds
  55. 55The partial pressure of Oxygen?20.93 %
  56. 56Partial Pressure of carbon dioxide CO2.03%
  57. 57Partial Pressure in nitrogen79.04%
  58. 58Barometric Pressure760 torr
  59. 59Barometric pressure of oxygen159 torr
  60. 60Barometric pressure of carbon dioxide CO2.2 torr
  61. 61Barometric Pressure of Nitrogen?600 torr
  62. 62What does gas exchange consist of?Diffusion and Partial Pressure
  63. 63Diffusiongases tend to diffuse from area of higher concentration to area of low
  64. 64Ventilatory MechanicsPressure and Volume are inversely directly related, one goes up and one must go down, wise versa
  65. 65InspirationExpanding of lungs
  66. 66When in inspiration does the pressure decrease or increase?decrease (open up, expand)
  67. 67ExpirationDeflation of lungs
  68. 68When in expiration does the pressure decrease or increase?increase
