What happens to the oxygen atoms from glucose?

Answer 1

What happens when glucose breaks down? Or what happens when glucose converts to starch? Or are you talking about some other situation?

Since this is not my area of expertise, I searched Google under the key words "glucose 'oxygen atoms'" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. If not, you might try your own search. Thanks for asking.
