The second half of the sentence about energy storage and accumulation

What is the second law of thermodynamics?

The second law of thermodynamics states that every time energy is transformed from one form to another, some of that energy is converted to heat. That means there is never 100% conversion of one form of usableenergy to another. Because heat is not available to do work, the usable amount of energy is decreased each time an energy conversion occurs.

What happens when 2-phosphoglycerate loses water?

If 2-phosphoglycerate loses water from its structure, it undergoes a dehydration reaction catalyzed by enolase. This results in the formation of a double bond, increasing the potential energy in the remaining phosphate bond, and produces phosphoenolpyruvate (PEP).

How does enolase catalyze 2-phosphoglycerate?

Enolase catalyzes the ninth step by causing 2-phosphoglycerate to lose water, resulting in the formation of phosphoenolpyruvate (PEP). This is a dehydration reaction that increases the potential energy in the remaining phosphate bond.
