The Thing Posted December 11, 2005 Share Posted December 11, 2005 How much energy does ATP give off when it changes to ADP? Can we somehow harness that energy to, say, power nanobots? Is this an exploitable area. I'm asking because I'm considering doing a project on this in a university lab hopefully. Any suggestions is welcome. How can I actually SHOW that the energy can be used? How can I convert the heat that ATP gives off to electricity efficiently? And how much ATP is needed to power say a very small lamp (battery powered ones) Link to comment Share on other sites More sharing options...
ecoli Posted December 11, 2005 Share Posted December 11, 2005 http://en.wikipedia.org/wiki/Adenosine_triphosphate According to Wikipedia, nanotechnology is working on how to employ ATP to power pacemakers... sounds similiar to what you want.

Yggdrasil Posted December 11, 2005 Share Posted December 11, 2005 The (delta)G for the hydrolysis of ATP is about -30.5 kJ/mol. Link to comment Share on other sites More sharing options...
atp_master Posted December 13, 2005 Share Posted December 13, 2005 What would happen if you injected pure ATP into your brain? Link to comment Share on other sites More sharing options...
Bluenoise Posted December 13, 2005 Share Posted December 13, 2005 Well since I don't believe it would have any way of getting into the cells you'd probably just pee it out. Correct me if I'm wrong but I'm pretty sure there is not way for our cells to transport atp over the cell membrane. Link to comment Share on other sites More sharing options...
atp_master Posted December 13, 2005 Share Posted December 13, 2005 But if there was a way to inject ATP directly into the brain cells, how do you think the recipient would react to such an energy surge within the brain itself? Link to comment Share on other sites More sharing options...
ecoli Posted December 13, 2005 Share Posted December 13, 2005 What would happen if you injected pure ATP into your brain? Im guessing you'd suffer from sort of of medical side effect from getting something injectedin your brain... besides, you're body gets enough energy from the food, why would you need a different source?

BhavinB Posted December 13, 2005 Share Posted December 13, 2005 There are ways of powering things with ATP. Go look up chemical motors. Friend of mine is working on a linear actuator powered by ATP. Link to comment Share on other sites More sharing options...
Bluenoise Posted December 13, 2005 Share Posted December 13, 2005 But if there was a way to inject ATP directly into the brain cells, how do you think the recipient would react to such an energy surge within the brain itself? Depends on how much. Just a little more? It would go through this reaction. ATP + AMP = 2 ADP Like there are buffers and controls to keep ATP levels constant. Glycolysis would pretty much stop until the basline was regained. Some of the excess would be funnelled into gluconeogenesis for energy storage. But not much since storage capacity of neurons is pretty limited. Way to much more? It would kill you. But in no way would it make your brain work better (If that's what you're looking to hear). Well unless it was deficient in the first place. It would be a baaaaad idea. plus what E. coli said about general negative effects of having a needle poking into your brain.

The Thing Posted December 14, 2005 Author Share Posted December 14, 2005 Wow, an ATP powered linear actuator? How much energy is produced from that stuff if I, say, put 100g of ATP decompsing into ADP in a jar of water to heat the water to use the steam to drive a turbine? How does one extract ATP from cells? Or can you synthetically, er, synthesize it and use that? I would suppose that extracting from cells wouldn't give you a pound all at once, so how do I get the ATP to power a motor? Link to comment Share on other sites More sharing options...
BhavinB Posted December 14, 2005 Share Posted December 14, 2005 Ya, I'm not in the field, but I'm sure you can easily find the information with any university library account. But just conceptually, you'd need a certain concentration of ATP, not mass. Plus, the active components of any device will have something similar to cells and proteins to convert the ATP.
