What is an adenosine triphosphate? I don't understand the fancy definitions. Can some one please simplify it for me? Thanks!
This site looks fairly easy for a biology student to understand.

Certainly! Adenosine triphosphate, or ATP, is a molecule that serves as the main energy currency of living organisms. It is often referred to as the "energy currency" because it stores and supplies the energy needed for various cellular processes.
Now, let's break it down a bit further:
1. Adenosine: This is a compound made up of adenine, a nitrogenous base, and a sugar called ribose.
2. Triphosphate: This refers to the presence of three phosphate groups attached to the adenosine molecule.
The high-energy bonds between these phosphate groups are what make ATP an efficient and readily available source of energy. When one of these phosphate groups is broken off through a process called hydrolysis, ATP is converted into adenosine diphosphate (ADP) and inorganic phosphate (Pi), releasing energy in the process. The energy released from ATP hydrolysis is then utilized by cells to perform various functions, such as muscle contraction, active transport, and synthesis of molecules.
In summary, ATP is a molecule found in all living organisms that acts as a universal energy carrier by releasing energy when one of its phosphate groups is removed, enabling cells to perform essential functions.
