How would you explain the connection between glucose entering the body and energy created by the body to a friend, using your new biochem knowledge?

Glycolysis begins by an input from either dietary glycogen and starch or glycogen stored in your cells. The glycolysis linear reactions occur in 10 steps. The first reaction uses water to break apart glucose molecules known as hydrolysis. A phosphate group is removed from an ATP molecule of energy producing ADP. This removed phosphate group is then added to the glucose molecule forming Glucose-6-phosphate (G6P). In reaction 2, an isomerase enzyme is used that creates an isomer of G6P. An isomer has the same number of atoms and types of atoms but is configured differently. The isomer created is D-Fructose-6-phosphate (F6P). In reaction 3, 1 ATP is used to phosphorylate F6P. Most phosphorylation reactions are done so via kinases which can add phosphate groups. D-Fructose-1,6-biphosphate is created. It is important to note that the product of the previous reaction becomes the reactant of the next. Glycolysis reaction 4 cleaves the F1,6P by using an aldolase creating Dihydroxyacetone phosphate and D-Glyceraldehyde-3-phosphate (D3P) which are isomers of eachother. In reaction 5 only D3P is formed and can then be used by reaction 6. This reaction is a redox reaction. These two reactions of adding oxygen and adding hydrogen happen together. Step 7 uses a kinase to remove the phosphate group of the 2 molecules creating 2 ATP molecules. Reaction 8 isomerases the product of the previous step. For the next reaction, the removal of water, dehydration, occurs. Finally, in reaction 10 hydrolysis and phosphorylation occur. The net gain of glycolysis is 2 ATP and 2 molecules of Pyruvate created. Gross gain is 4 ATP, but because the process of glycolysis uses 2 ATP, this results in the net gain of 2. Although the process seems complicated and overwhelming, what is important to take away is the idea that through glycolysis, energy is created that is then used by the body from molecular activities to muscle movements. By looking at how glycolysis works, I have great appreciation of how our bodies function.
