On the page I said that "later prokaryotes invented glycolysis which employs ATP and is used to this day". I wonder if the earlier chemoautotrophs already used ATP for energy conversion? --AxelBoldt |

I wonder if the earlier chemoautotrophs already used ATP for energy conversion? --AxelBoldt All living things contain ATP, which is used in RNA production, and I would be very surprised if it has not always been used in energy conversions, as something fundamental to most biological pathways. Of course, some other things could have been more important in the past, like GTP. Out of curiosity, are we saying the earliest prokaryotes had no form of glycolysis? Because they certainly needed to be able to synthesize some sugars, and so break them down, and I've never heard of any other pathway, although it admits some variation. --Josh Grosse |
