The connection between glucose entering the body and energy created by the body

(Structural Formula of Glucose) 

Glucose enters the cell by a process of many reactions called glycolysis. Glucose enters the body and a phosphate attaches to the glucose molecule. This is a way for the cell to acquire energy because there is loss of energy converting ATP into ADP when the phosphate attaches to the glucose molecule. From this process the glucose will convert to fructose and another phosphate will then attach and cause loss of energy.

The two molecules that are involved in the process to create ATP when a phosphate is lost is called dihydroxyacetone and glyceraldehydes. These two molecules are split separately and rearranged into isomers, created into two of the same molecules. For  every lose of a phosphate,  two molecules of ATP are created.
