Energy Systems

ATP Hydrolysis

the process of ATP breaking down into ADP+P+energy+heat, and the use of creatine for ADP to form ATP

Cellular respiration

process by which the chemical energy of “food” molecules is released and partially captured in the form ATP

ATP storage

The energy system that we use first. It powers the first few seconds of activity.

ATP/CP system

The energy system that takes over dominance after 2 seconds and provides energy until the creatine runs out after about 5 seconds. 

Glycolytic Systems

In cytoplasm, glucose turns into pyruvate through glycolysis. If no O2 is present during the process, pyruvate will turn into lactic acid/ethanol+2ATP. If O2 is present, pyruvate will turn into 30-32 ATP in the mitochondrion.
