Adenosine triphosphate (ATP) consists of adenine, ribose and three phosphate groups. Hydrolysis releases more energy, which is the most direct energy source in organisms.
The elements of ATP are: C, H, O, N, P, and the molecular abbreviation A-P~P~P, where A stands for adenosine, T stands for triple (the initials of English triple T), P stands for phosphate group, "-"stands for ordinary phosphate bond, and "~" stands for a special chemical bond, which is called high-energy phosphate bond (energy is greater than 29.32).
Extended data:
There is about 50.7gATP in the human body, which can only maintain strenuous exercise for 0.3 seconds. ATP and ADP can be rapidly transformed and kept in balance. The process of converting ADP into ATP requires energy.
ATP can be formed when ADP combines with phosphate group and obtains 8 kcal energy.
For animals, people, fungi and most bacteria, it comes from the energy released by the decomposition of organic matter when cells breathe. For green plants, in addition to the energy released by respiration, the conversion of ADP into ATP in chloroplasts also depends on the light energy during photosynthesis.
When ATP is hydrolyzed, ADP is formed and phosphate is released, and energy is also released. These energies will be used in cells, and the movement generated by muscle contraction, the activity of nerve cells and all other activities of living beings use the energy generated by ATP hydrolysis.
