Discussion Overview

The discussion revolves around the nature of atoms in biological organisms, specifically whether organisms maintain the same atoms over time or if they are constantly changing. Participants explore the implications of eating and how it affects the atomic composition of the body.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant questions whether organisms have the same atoms consistently or if they are always changing, particularly in relation to food intake.
  • Another participant suggests that while many atoms are recycled, some end up in molecules that the body disposes of, indicating a dynamic process of atomic incorporation.
  • A later reply supports the idea that atoms are mostly replaced over time, noting a cycle of regeneration for cellular components, with some atoms, like those in DNA, being retained longer.

Areas of Agreement / Disagreement

Participants appear to agree that there is a cycle of atomic replacement in organisms, but the specifics of this process and the retention of certain atoms remain nuanced and not fully resolved.

Contextual Notes

There are assumptions regarding the definitions of "recycled" and "retained" atoms that are not fully explored, and the time frame for atomic replacement is presented in a general manner without precise details.

I was just curious about atoms in biology. Do organisms have the same atoms all the time? Or are they always changing? When we eat do we gain new atoms etc. Sorry if this is a dumb question. I can't find anything on it maybe because it is to easy.

Both. Many are recycled over and over while others end up occasionaly in deadend molecules that the body would rather dispose of than try to handle. The food you eat dose in a real sense become part of you.
 
That is what I thought. Thanks
 
..they are mostly replaced..it is a constant cycle or regenesis for most cellular components...some are retained for longer periods of time (the atoms in DNA) but mostly...you get a new body every decade or so (slowly of course and not completely.)
