Explain why ATP is used as major power currency in many cellular reactions than GTP, TTP or TCP in cellular machinery?
Answers
The evolution of ATP was related to energy first before life development in the earliest time at 4.2 billion years ago, while the evolution of GTP was later because it needed oxygen atom in the GTP molecule (remember, the oxygen level in the atmosphere was very low at that earlier time!).
ATP can be easily broken down and multifunctional in aspect of energy delivering , Also there may be an evolutionary style that our cells and membranes have adapted to use ATP. ATP is known as adenosine triphosphate, and it is a molecule containing carbon, hydrogen, nitrogen, oxygen and phosphorus. ATP is the energy currency of the cell because, it is the most preferred energy molecule in the cell. In case GTP can be the best alternative when needed.
