definitions
- Power : amount of energy (ATP) produced in the unit of time. ENGINE HORSES.
- Capacity : total amount of ATP that could be synthesized if all the energy substrates available for that metabolic pathway were consumed. HOW MANY GASOLINE IS IN THE TANK.
- Energy yield : ATP moles synthesized per mole of initial substrate consumed. KM WITH A LITER.
- Latency : time required to obtain the maximum power that can be delivered by the metabolic pathway
- Refreshment : time required for reconstitution of the system
Synthesis mechanisms of ATP | Power in moles of ATP per minute | Capacity in moles of total ATPs | Yield in moles of ATP per mole of substrate | Latency | refreshments |
Anaerobic alactacid | 3.8 | 0.4 | 1 mole of ATP per mole of phosphocreatine | Fractions of a second | Very short (a few sec.) |
Anaerobic lactate | 1.9 | 1.2 | 2 mol of ATP per mole of glucose 3 moles of ATP per mole of glucose from glycogen | 10-15 seconds | Short (20-40 minutes) |
Aerobic | 1 | Infinity | 36-38 moles of ATP per mole of glucose 129 moles of ATP per mole of palmitate | 45-180 seconds | Very long (36-48 hours) |
