That really has nothing to do with my question. I asked how organisms developed this ability. I'm also not going to read the entire ATP article!
Evolution is a process that has been going on since the very miliseconds after the Big Bang started. To be able to explain how food evolved to a creationist/intelligent designist requires you to be able to explain every evolutionary advancement ad infinitum back to singularity. If you don't have the ability to do so...your opinion will be wrong. If you start by providing the answer to the initial question you will have infinite more work to do. It's a catch 22. Don't fall into the trap.
Find out first if they are willing to change their opinion if you explain the answer to the original question. "If I can explain that to you will you reconsider?" If the answer is no...don't waste your time. If the answer is yes...proceed with caution
I think therefore I am...busy
