Limitied Innate ATP?

Postby Edher » Wed Feb 16, 2005 7:15 am

Saludos,

Are we born with a certain amount of ATP? I know that Glycosis, the Citric Acid Cycle and Oxidative Phosphorylation account for recycling already-existing ADP and P molecules into ATP, but where do we get more raw materials of ATP?

Thank You,
Edher

When we born, we start taking oxygen in and give CO2 out. In our mother's uterus, we take glycose and oxygen form our mother by exchanging CO2 and waste products. And make our cellular respiration.

There is no "limit" to ATP that we have. The way we get the energy from ATP is that it is held in an unbalanced equilibrium reaction with adenosine diphosphate (ADP). When allowed to balance out, energy is released. Mitochondria is responsible for working the reaction in reverse so that ADP is turned back into ATP.

Saludos,

The original question has not been answered. I'll be more thorough when I come back from taking my test.

I don't think any recycling process is completely efficient. Also when cells die, not all are recovered i.e. skin cells. Therefore atp should be something that is constantly produced by the body.

Sure it is. Adenine is constantly synthesized, not only to keep ADP/ATP level but also because it is the same molecule (and sythesis pathways) that make for the Adenosine which used to buiild DNA and RNA...
