|---|---|---|---|---|---|
| Why must glycogen also be present when using fats and a fuel source? | Transport of fatty acids slow due to poor solubility, therefore arrive at muscle in insufficient quantities to sustain contraction
🗑
|
||||
| What are the three energy systems used by the body to resynthesis ATP? | ATP-PC (alactic system)
lactic acid system
aerobic (oxidative) system
🗑
|
||||
| Who would use the ATP-PC system? | 100m sprinter
gymnast performing a vault
activity that last 10 seconds or less
🗑
|
||||
| What type of activity might use predominantly the lactic acid system | 400m/ squash rally
high intensity activity that lasts 1-2 minutes
🗑
|
||||
| How many ATP molecules does the lactic acid system produce? | two
🗑
|
||||
| What fuel sources might the aerobic system use? | Glycogen
fats
protein
🗑
|
||||
| What are the two key stages in aerobic systems that occur in the mitochondria? | Krebs’s cycle
electron transfer system
🗑
|
||||
| What events take place in the Krebs’s cycle | Oxidation of acetyl-coenzyme-A
production of CO2
resynthesis of ATP
🗑
|
||||
| What events take place in the electron transfer system | Water is formed / resynthesis of ATP
🗑
|
||||
| Advantages of Aerobic system | More ATP resynthesis compared to anaerobic
Body has substantial stores of glycogen and triglycerides
oxidation of glycogen & triglycerides produces no fatiguing by products
🗑
|
||||
| Disadvantages of aerobic system | Takes time to supply sufficient O2 for some activities
fatty acids require more oxygen
fatty acids slow transport
need for glycogen as well as fats due to poor solubility.
🗑
|
||||
| Disadvantages of LA system | Accumulation of lactic acid making enzymes acidic inhibits energy production activity must reduce in intensity or stopped to remove LA
small amount of energy inside glycogen molecule can be released
🗑
|
||||
| Advantages of LA system | ATP resynthesis relatively quickly
anaerobic does not need to wait for O2
lactic acid can be converted back into liver glycogen or pyruvate and enters aerobic system Lactic acid system can be used for a burst of energy in endurance events
🗑
|
||||
| Advantage of ATP-PC system | Rapid resynthesis
PCr stores recovered quickly
anaerobic process does not need to wait for O2
no fatiguing by products
🗑
|
||||
| Disadvantages of ATP-PC system | Limited supply of PCr (10seconds)
Resynthesis of PCr only when sufficient O2 present
only 1 mole of ATP can be recycled by 1 mole of PCr
🗑
|
||||
| How many ATP molecules doe s the ATP-PC system produce | One
🗑
|
||||
| How many ATP molecules does the aerobic system produce | 38
🗑
|
||||
| The ATP PC system how long will it last and type of intensity? | 8-10 seconds high intensity
🗑
|
||||
| The Aerobic system how long will it last and type of intensity? | over 3 minutes low intensity
🗑
|
||||
| The Lactic acid system how long will it last and type of intensity? | up to 3 minutes medium to high intensity
🗑
|
||||
| What fuels sources i used by ATP-PC system | Phosphocreatine
🗑
|
||||
| What fuels sources can be used by the aerobic system | Glycogen and Fats
🗑
|
||||
| Name the two anaerobic energy systems | Lactic acid and ATP-PC
🗑
|
||||
| ATP is broken down into what to produce energy? | ADP
🗑
|
||||
| How many ATP molecules produced in Krebs cycle? | 2
🗑
|
||||
| How many ATP molecules produced in Electron transfer chain? | 34
🗑
