Question

ATP has been called the energy currency of life. That indicates most organisms on earth use ATP as their energy source. What does this indicate about the origin of ATP and its biological importance?

Answer 1

This implies that atp must have been there since the beginning of life. It implies that every cell that requires energy for performing an action such as aerobic respiration, there has to be presence of atp. This could also be referred to as the energy liberating molecule in cells. The biological significan of atp is that in order to carry out any reaction in the body requiring energy atp would be required, it helps in breakdown of the food molecules fast wre consumed, to replinishing energy in the muscles when these would be carrying out vigorous functions. Atp gets hydrolysed to adp and pi.
