g As you begin to run on a treadmill in the gym, your muscles begin using glucose stored in your muscle cells. The immediate need for ATP to provide energy to your muscle cells starts with glycolysis, which produces ATP by

through the glycolysis process

Explanation:

Glycolysis processes are catabolic processes where energy reserves are broken forming more simple molecules such as ATP, so that these are ideal energy sources for rapid consumption.

ATP is considered as the energy currency, it is called adenosine tri-phosphate and the breakdown of a phosphor by means of a kinase is what causes great energy to be released for muscle contraction.

not: both offer magnification to the atomic level.
