How Enzymes Handle the Energy Derived from the Cleavage of High-energy
When the concept of phosphate compounds of high and low energy was formulated by Lipmann in 1941, it was thought that the energy level of a phosphate residue would always be the same, and on the basis of the data available at that time, the possibility that the energy of hydrolysis might change in the surface of an enzyme was not taken into consideration.

What is high-energy phosphate?
High-energy phosphate can mean one of two things: The phosphate -phosphate (phosphoanhydride/phosphoric anhydride/macroergic/ phosphagen) bonds formed when compounds such as adenosine diphosphate (ADP) and adenosine triphosphate (ATP) are created.
What is a high-energy phosphate pool?
The compounds that contain these bonds, which include the nucleoside diphosphates and nucleoside triphosphates, and the high-energy storage compounds of the muscle, the phosphagens. When people speak of a high-energy phosphate pool, they speak of the total concentration of these compounds with these high-energy bonds.
What are phosphate bioenergetic pathways?
A general representation of aerobic, anaerobic and high energy phosphate bioenergetic pathways. The high-energy phosphate system (also known as the phosphagen or anaerobic alactic system) is characterized by the substrates that the system uses to produce energy.
What are high-energy phosphate bonds?
High-energy phosphate bonds are usually pyrophosphate bonds, acid anhydride linkages formed by taking phosphoric acid derivatives and dehydrating them. As a consequence, the hydrolysis of these bonds is exergonic under physiological conditions, releasing Gibbs free energy. [citation needed]
What phosphate bonds are used in biological systems?
In biological systems, energy is mainly saved and spent in the currency of high-energy phosphate bonds: acyl phosphates, phosphoanhydrides, phosphoamides, carbamoyl phosphate, and phosphoenolate, all of which were known in 1941 (Lipmann, 1941). Phosphorus forms long covalent bonds with oxygen (Wald, 1962).
Do high energy phosphates provide anaerobic energy to the muscle system?
High energy phosphates contribute anaerobic energy to the muscle system. Very high power outputs can be produced on demand, but these outputs can only be maintained for very short durations. Small amounts of blood glucose and large amounts of muscle glycogen can also supply energy rapidly.
