|
What is the fuel for the aerobic system? |
Glycogen, glucose, free fatty acids (20% more oxygen) |
|
|
Where does the reaction take place for the aerobic system? |
Aerobic gycolysis- sarcoplasm Krebs- matrix ETC- cristae |
|
|
What enzyme controls the reaction for the aerobic system? |
PFK |
|
|
Bi-products of aerobic energy system? |
water and carbon dioxide |
|
|
How many ATP can be re-synthesized in aerobic system? |
38 ATP |
|
|
What duration and intensity can this energy system can provide energy for?
|
Sub-maximal- low/mod intensity High duration - unlimited |
|
|
advantages for the aerobic energy system |
1. No fatiguing bi-products- water and carbon dioxide is easily removed. 2. Provides energy for a high duration (unlimited) 3. Large ATP re-synthesis. 38 ATP from 1 glucose. 4. Convert carbs and fat into energy |
|
|
disadvantages for the aerobic energy system
|
1.Slower rate of ATP re-synthesis because Requires more oxygen (20% more for FFAs) More complex series of reactions 2. At the start of exercise, unable to re-synthesize ATP due to initial delay of O2 from cardiovascular system. |
|
|
What is the fuel for the LA system?
|
Glycogen/ glucose |
|
|
Where does the reaction take place for the LA system?
|
Sarcoplasm |
|
|
What enzyme controls the reaction for the LA system? |
PKF and LDH |
|
|
Bi-products of LA system?
|
Lactic Acid (fatiguing) |
|
|
How many ATP can be re-synthesized in LA system?
|
2 ATP |
|
|
advantages for the LA system?
|
Resythesises 2 ATP more than PC system Doesn't require oxygen Fewer reactions than aerobic system so quicker supply of energy. |
|
|
disadvantages for the LA system?
|
Cant produce energy as quick as ATP/PC system LA is fatiguing bi-product. |
|
|
What is the fuel for the PC system?
|
PC |
|
|
Where does the reaction take place for the PC system?
|
sarcoplasm |
|
|
What enzyme controls the reaction for the PC system?
|
Creatine Kinase |
|
|
Bi-products of PC system? |
P and C |
|
|
What duration and intensity can the LA system can provide energy for?
|
Near maximal 1-2 mins |
|
|
What duration and intensity can the PC system can provide energy for?
|
Maximal exercise up to 10 secs |
|
|
advantages for the PC system?
|
Doesn't require oxygen PC stored in sarcoplasm- readily available source of energy. No fatiguing bi-products PC can be quickly re-synthesized so recovery time is quick. 100%- 2/3 mins |
|
|
disadvantages for the PC system?
|
Small amount of PC and ATP stored in sarcoplasm. 1 PC re-synthesizes 1 ATP Only provides energy to re-synthesize ATP for up to 10 secs |
