cell 3

  1. 1. Cellular Respiration
  2. 2. <ul><li>What is Cellular Respiration </li></ul><ul><li>Why is it important to me </li></ul>
  3. 3. Key Terms <ul><ul><li>Aerobic Respiration </li></ul></ul><ul><ul><li>Anaerobic Respiration </li></ul></ul><ul><ul><li>ATP (Adenosine Tri-phosphate) </li></ul></ul><ul><ul><li>Glycolysis </li></ul></ul><ul><ul><li>Pyruvate </li></ul></ul><ul><ul><li>Fermentation </li></ul></ul><ul><ul><li>Mitochondria </li></ul></ul><ul><ul><li>Krebs Cycle </li></ul></ul><ul><ul><li>Respiration </li></ul></ul><ul><ul><li>Ventilation </li></ul></ul>
  4. 5. <ul><li>The point of cellular respiration is to harvest electrons from organic componds such as glucose and to use that to make a molecule called ATP. </li></ul><ul><li>ATP in turn is used to provide energy for most of the immediate work a cell does </li></ul>
  5. 6. Bringing it together <ul><ul><li>Cells </li></ul></ul><ul><ul><li>Nutrition </li></ul></ul><ul><ul><li>Metabolism </li></ul></ul><ul><ul><li>Respiration </li></ul></ul>
  6. 8. <ul><ul><li>All cells require a continous supply of oxygen </li></ul></ul>
  7. 9. Normal Values <ul><li>PH: 7.35 - 7.45 </li></ul><ul><li>Pco2 : 35 - 45 </li></ul><ul><li>Hco3 : 22- 26 </li></ul><ul><li>Po2: 80 - 100 </li></ul>The air we breath is made up of 1. Oxygen 21% 2.Carbon Dioxide 0.03% 3. Nitrogen 79% Other .003%
  8. 10. <ul><ul><li>Oxygen is drawn into the body through the mouth and nose </li></ul></ul><ul><ul><li>Once it reaches aveoli, O2 is able to tranfer into the blood and taken to the cells </li></ul></ul><ul><ul><li>This is known as tissue oxgenation or cell oxygenation </li></ul></ul>
  9. 11. <ul><ul><li>Low oxygen levels is called hypoxia </li></ul></ul><ul><ul><li>In low oxygen conditions anaerobic cellular oxygenation will occur generating the waste prodct lactic acid </li></ul></ul><ul><ul><li>If low oxygen continues it will lead to a metabolic acidosis resulting in cell death </li></ul></ul>
  10. 12. If you cant Breath Nothing else matters
  11. 13. <ul><li>If you stop or severly slow your breathing your </li></ul><ul><li>Ph will go Down, Pco2 up and Po2 will go down </li></ul><ul><li>PH: 7.28 </li></ul><ul><li>Pco2: 50 </li></ul><ul><li>Po2: 60 </li></ul>
  12. 14. <ul><li>If you hyperventilate your ph will go UP, Pco2 DOWN, PO2 UP </li></ul><ul><li>PH : 7.55 </li></ul><ul><li>Pco2: 25 </li></ul><ul><li>Po2 : 100 </li></ul>
  13. 16. Works Cites <ul><li>Egans Fundamentals of Respiratory Care </li></ul><ul><li>mosby 2003 </li></ul><ul><li>Blood Test </li></ul><ul><li>www.healthcare.org </li></ul><ul><li>Biology : the Unity and diversity of Life </li></ul><ul><li>star/Taggart/Evers Twelfth Edition </li></ul>
