Energy Systems. Flashcards
Energy Continuum. Aerobic System. Lactate Anaerobic System. OBLA. ATP-PC System.
What is the Aerobic Equation?
Glucose + Oxygen = Energy + Carbon Dioxide + Water.
What is the Anaerobic Equation?
Glucose = Energy + Lactic Acid.
Define ATP.
Adenosine Triphosphate.
What is the equation for ATP?
A-P-P-P
Define ADP.
Adenosine Diphosphate.
List the 3 Phases of the Aerobic Energy System.
- Glycolysis.
- Krebs Cycle.
- Electron Transport Chain.
Explain the Glycolysis Phase of the Aerobic Energy System.
Glycogen reacts with Glycogen Phosphorylase to make Glucose.
Glucose and Phosphofructokinase react to make Pyruvic Acid + 2 ATP.
Explain the Krebs Cycle Phase of the Aerobic Energy System.
First becoming Oxoloacetic Acid and then Citric Acid.
CO2 and Hydrogen are made along with 2 ATP.
Explain the Electron Transport Chain of the Aerobic Energy System.
The hydrogen is split into positively charged H ions, and negatively charged electrons. Oxygen reacts with the H ions to make water. The electrons undergo a series of reactions which gives enough energy for 34 ATP.
How long does the Aerobic Energy System last?
Hours.
List the Advantages of the Aerobic Energy System.
Great for Low Intensity Work.
No Fatiguing by-products.
38 Total ATP.
List the Disadvantages of Aerobic Energy System.
ATP is made slowly.
Recovery can take a Long Time.
Explain the Lactate Anaerobic System.
Glycogen reacts with Glycogen Phosphorylase to make Glucose.
Glucose and Phosphofructokinase react to make Pyruvic Acid + 2 ATP.
Without enough O2, the Pyruvic Acid reacts with Lactate Dehydrogenase to make Lactic Acid.
With enough O2, the Pyruvic Acid makes Mitochondria.
What does OBLA Stand for?
Onset of Blood Lactate Accumulation.
Define OBLA.
The point at which lactic acid begins to rapidly accumulate in the blood.
How long does the Lactate Anaerobic System last?
3 Minutes.
List the Advantages of the Lactate Anaerobic System.
Great for High Intensity Work.
ATP produced at a Fast Rate.
List the Disadvantages of the Lactate Anaerobic System.
Poor Yield - only 2 ATP.
Recovery can take up to an hour.
Harmful Lactic Acid is made.
Explain the ATP-PC System.
Phosphocreatine is broken down by the enzyme creatine kinase into creatine, phosphate, and energy.
The phosphate and energy combine with an adenosine diphosphate [ADP] to make ATP.
This is called a coupled reaction.
How long does the ATP-PC System last?
90 Seconds.
List the Advantages of the ATP-PC System.
Great for high intensity wur.
ATP is produced at a fast rate.
No fatiguing by-products.
PC stores are quickly replenished after exhausion.
List the Disadvantages of the ATP-PC System.
Limited duration and stores .
Yield is only 1 ATP per cycle.
