What are the three main pathways of ATP production?
In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes—glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation—to produce ATP.
What is the ATP CP system?
The ATP-PC system uses a stored molecule in the muscle called creatine phosphate (CP) to resynthesise ATP. It is the breakdown of this molecule that releases the energy needed to rejoin the ADP and free phosphate to form ATP.
What is the activities of ATP CP?
Energy systems used in sports
| Sport | ATP-PC | Anaerobic Glycolytic |
|---|---|---|
| Basketball | 60 | 20 |
| Field events (shotput, discuss, javelin) | 90 | 10 |
| Golf swing | 95 | 5 |
| Gymnastics | 80 | 15 |
How long does ATP CP last?
The Alactic Energy System Adenosine Triphosphate (ATP) stores in the muscle last for approximately 2 seconds. The resynthesis of ATP from Creatine Phosphate (CP) will continue until CP stores in the muscles are depleted, approximately 4 to 6 seconds. This gives us around 5 to 8 seconds of ATP production.
How do you recover ATP?
ATP that is already present in the muscle is used and recycled by breaking down creatine phosphate. Once we have depleted our ATP (through a 1 rep max attempt, for example), it takes at least 3 minutes of rest for muscles to recover the maximum amount possible of ATP and creatine phosphate.
How do you calculate total energy in nutrition?
The amount of grams of each energy source (fat, carbohydrate, and protein) and the amount of energy per gram of each energy source is given on the label. Multiply the grams by the Energy per gram to obtain the Energy.
Is voltage the force?
Voltage is the electrical force that causes free electrons to move from one atom to another. Just as water needs some pressure to force it through a pipe, electrical current needs some force to make it flow. “Volts” is the measure of “electrical pressure” that causes current flow.
Is current an energy?
Many reference books claim that electricity is a type of energy and that electric current is a flow of energy, however, this isn’t exactly correct. Yes, electrical energy does exist, but this energy can’t be called “Electricity,” since Coulombs of electricity are very different from Joules of electromagnetic energy.
What is relationship between voltage and energy?
Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since ΔPE = qΔV.
