Really ? Can you link to it ? <| sep |> Yeah I know basically any chemical reaction can work as an energy carrier , but there ' s obviously been a selective pressure to using NTP ' s . Availability of nucleotide bases ? After that it seems more or less luck of the draw which was selected for given a more common carrier is more efficient . How is the ATPADPPi disequilibrium maintained ? Just by virtue of having more ADP than energetically necessary ? <| sep |> That ' s the problem . Ultimately it ' s her decision what she wants to do if she wants to tell me to block YouTube and get a list of videos to download . I guess I could let her know just downloading YouTube videos is stealing since it ' s taking away from content creators . Which makes plenty of sense . Saves money on buying DVDs for specific programs , and still passes knowledge where it needs to be . Brick walls are not easy to talk to though .
