What happens all that energy? How come respiration from glucose (or any pathway)

Question

What happens all that energy? How come respiration from glucose (or any pathway) is accomplished in many small steps instead just of one big reaction? just Should the Delta G degree for the entire reaction change if it is done in many little steps rather in one big step? in the body, the first step of glycolysis, glucose needs to be converted into glucose-6-p should actually be an "endergonic" reaction. Yet the enzyme hexokinase knows how to "couple" two reactions together to get what should be an endergonic reaction to take. Explain this coupling process. Why are chemicals assumed to contain 'potential energy"? May some chemical bonds possess more potential energy than others? During oxidative pathways (reactions) some of the energy released is chemically conserved by channeling, it into the formation of high energy covalent bonds. These organic chemicals that contain one or more high energy bonds are termed 'activated the most famous and useful activated earner in the cell is What type of high energy bond(s) does it contain? Through what "process" is this energy released? And, in general, what should happen to (some of) this energy when it is released?

Explanation / Answer

Chemical are supposed to contain potential energy because they contain energy which are stored and have the ability to do the work in future which can include to react with other chemicals.

No,all chemicals have the same potentia lenergy. as the gravity remains the same.

They are called as activated catalysts.

Adenosine triphosphate(ATP)is the famous and useful activated carrier.
