ATP (2)

Hello and welcome everyone...how do we ignite the correct source
of energy and at the proper time of need. When your run aerobically, as long as there is plenty of oxygen, ATP will be
manufactured from the breakdown of fat and sugar. This system can produce almost limitless amounts of ATP if you need energy
for endurance exercise, count on the aerobic system. Lactate System...in contrast, when you run anaerobically, the lack of oxygen not only turns off fat burning, it also blocks pyruvate from
entering the Krebs cycle. Pyruvate builds up and is converted to
lactic acid, or lactate. The only ATP produced comes from the burning of sugar halfway, so the amount of energy produced is
limited. The beauty of this system is that it doesn't have to wait for oxygen, so ATP is produced very fast. If you need fresh ATP in a
hurry, the lactate system will kick in to burn lots of sugar molecules
quickly. You will get quick energy...but it won't last. Creatine-
Phosphate...third method to build fresh ATP. will continue in part
three, next week.
Have a meaningful life everyone...Jimmy O
