Cellular Respiration
What is Cellular Respiration
Why is it important to me
Key Terms1.Aerobic Respiration2.Anaerobic Respiration3.ATP (Adenosine Tri-phosphate)4.Glycolysis5.Pyruvate6.Fermentation7.Mitochondria8.Krebs Cycle9.Respiration10.Ventilation
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.
ATP in turn is used to provide energy for most of the immediate work a cell does
Bringing it together
1.Cells2.Nutrition3.Metabolism4.Respiration
1.All cells require a continous supply of oxygen
Normal Values
PH: 7.35 - 7.45 Pco2 : 35 - 45Hco3 : 22- 26Po2: 80 - 100
The air we breath is made up of
1. Oxyegen 21%2.Carbon Dioxide 0.03%
3. Nitrogen 79%Other .003%
1.Oxygen is drawn into the body through the mouth and nose2.Once it reaches aveoli, O2 is able to tranfer into the blood and taken to the cells3.This is known as tissue oxgenation or cell oxygenation
1.Low oxygen levels is called hypoxia
2.In low oxygen conditions anaerobic cellular oxygenation will occur generating the waste prodct
lactic acid3.If low oxygen continues it will lead to a metabolic acidosis resulting in
cell death
If you cant Breath
Nothing else matters
If you stop or severly slow your breathing your
Ph will go Down, Pco2 up and Po2 will go down
PH: 7.28Pco2: 50Po2: 60
If you hyperventilate your ph will go UP, Pco2 DOWN, PO2 UP
PH : 7.55Pco2: 25Po2 : 100
