Alactacid System provides energy for the first 10 seconds of your activity - burns ATP supplies in your muscles. From there it goes to the Lactic Acid System which provides energy for the next 1 min of high intensity activity/3 min of moderate intensity activity - burns carbohydrates to provide energy. Any activity after that is powered by the Aerobic System which uses oxygen, glucose and body fats for fuels.

Actually, the lactic acid (or Anaerobic glycolosis) system burns glucose and glycolosis (stored glucose). The Aerobic system burns Carbohydrates and Fats.

all you need to know
Aspects of energy systems
ATP/PC
LACTIC ACID
AEROBIC
Fuel Source
Creatine Phosphate
Carbohydrates – stored in muscle and liver as glycogen, and
Glucose in blood
Carbohydrates – stored in muscle and liver as glycogen,
Fats and occasionally protein
Efficiency of ATP Production
Very quick ATP production
Quick ATP production
but fatigues drastically as
lactic acid levels rise
Slower ATP production but
endless supply
System Duration
10-15 seconds
High intensity
(95-100% max effort)
30sec – 3min
Relatively high intensity
(70-95% max effort)
Endless supply
Low/moderate level intensity
(less than 70% max effort)
Causes of Fatigue
Limited supply of:
ATP (90g lasts 1-2sec)
And
PC (120 lasts 8-10sec)
Accumulation of
Lactic Acid
Depletion of glycogen levels
and fat stores
By-Products
heat
Lactic Acid
CO2; water
Process and Rate of Recovery
50% recovery in first 30sec
Full recovery in 2mins
30mins – 2hours
Up to 48hours depending
on level of depletion

Glycoloysis is the break down of glucose!! Glycogen is stored in the muscles and liver if that's what you meant??
