|---|---|---|---|---|---|
| Anaerobic Metabolism ATP-PC System | This energy system is used for ATP production during high intensity, short duration exercise such as sprinting 100 meters.
🗑
|
||||
| Anaerobic Metabolism ATP-PC System | Phosphocreatine decomposes and releases a large amount of energy that is used to construct ATP.
🗑
|
||||
| Anaerobic Metabolism ATP-PC System | There is two to three times more phosphocreatine in cells of muscles than ATP.
🗑
|
||||
| Anaerobic Metabolism ATP-PC System | This process occurs almost instantaneously allowing for ready and available energy needed by the muscles.
🗑
|
||||
| Anaerobic Metabolism ATP-PC System | The system provides energy for muscle contraction for up to 15 seconds.
🗑
|
||||
| Anaerobic Metabolism ATP-PC System | The phosphagen system represents the most rapidly available source of ATP for use by the muscle. Reasons for this rapid availability are as follows:
🗑
|
||||
| Anaerobic Metabolism ATP-PC System | It does not depend on a long series of chemical reactions.
🗑
|
||||
| • Anaerobic Metabolism ATP-PC System | It does not depend on transporting the oxygen we breathe to the working muscles.
🗑
|
||||
| • Anaerobic Metabolism ATP-PC System | Both ATP and PC are stored directly within the contractile mechanisms of the muscle.
🗑
|
||||
| Anaerobic Glycolysis This energy system | is a major supplier of ATP during high intensity, short duration activities such as sprinting 400 or 800 meters.
🗑
|
||||
| Anaerobic Glycolysis | Stored glycogen is split into glucose, and through glycolysis, split again into pyruvic acid. The energy released during this process forms ATP.
🗑
|
||||
| Anaerobic Glycolysis The process does not require | oxygen. This system is nearly 50% slower than the phosphocreatine system and can provide a person with 30 to 40 seconds of muscle contraction.
🗑
|
||||
| Anaerobic glycolysis results in | the formation of lactic acid, which causes muscular fatigue.
🗑
|
||||
| • Anaerobic Glycolysis It | does not require the presence of oxygen.
🗑
|
||||
| • Anaerobic Glycolysis It uses only | carbohydrates (glycogen and glucose).
🗑
|
||||
| • Anaerobic Glycolysis It releases | enough energy for the resynthesis of only small amounts of ATP.
🗑
|
||||
| Aerobic Metabolism is used predominantly during | low intensity, long duration exercise such as running a marathon.
🗑
|
||||
| Aerobic Metabolism The oxygen system yields by | far the most ATP, but it requires several series of complex chemical reactions. This system provides energy through the oxidation of food.
🗑
|
||||
| Aerobic Metabolism The combination | of fatty acids, amino acids, and glucose with oxygen releases energy that forms ATP. This system will provide energy as long as there are nutrients to utilize.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
