What are the three energy systems in the body?
|
Phosphagen
Anaerobic Glycolysis Aerobic Energy |
|
|
What fuel is used for the Phosphagen System?

|
Carbs, Fats, Proteins
(All macronutrients) |
|
|
Immediate Energy System
|
Phosphagen System
|
|
|
In which site of the cell does the Phosphagen system occur?
|
Muscles - cytoplasm
|
|
|
In which site of the cell does anaerobic glycolysis occur?
|
Cytosol
|
|
|
In which site of the cell does aerobic occur?
|
Mitochondria
|
|
|
Short burst exercises use which system?
|
Phosphagen
|
|
|
Sprints use which system?
|
Anaerobic
|
|
|
Endurance events use which system?
|
Aerobic
|
|
|
Which system has the highest <b>rate</b> of energy production?
|
Rate - Phosphagen 1to1 ratio
|
|
|
Which system produces the most energy?

|
|
What are the general durations for each system?
|
Phosphagen - instantaneous
Anaerobic - seconds Aerobic - minutes |
|
|
What are the main causes of fatigue for each system?
|
Phosphagen - limited stores of pre-formed ATP and Cr-P
Anaerobic - limited stores of glycogen; lactic acid buildup Aerobic - resists fatigue; intensity and lack of fuel |
|
|
In what part of the cell does anaerobic metabolism occur?
|
Cytosol
|
|
|
Where does aerobic metabolism occur?
|
Mitochondria
|
|
|
What are the by-products of the aerobic system?
|
Aside from ATP, CO2 and H2O.
|
|
|
Is lactic acid a waste product? Explain.
|
Yes, it comes from Anaerobic glycolysis and when it builds up causes fatigue.

Beta Oxidation - fat
Deamination - protein Citric Acid Cycle - Acetyl CoA Electron Transport Chain - NADH, FADH |
|
|
Ergogenic popularly used?
|
Creatine. Increases anaerobic output. May cause diarrhea and muscle cramps.
