Homework Help: biology

Posted by Anonymous on Tuesday, October 20, 2009 at 2:39pm.

I have a question about reduced and oxidized chemicals and potenital enery.

Reduced have weaker PE because they hold on to their electrons
and oxidized have strong PE because they can let go electrons right?

If I am right then why is that CO2 has a low PE because Oxygen is more electronegative Carbon.

No one has answered this question yet.
