The other main product of yeast fermentation is alcohol.  This is in most
cases what eventually causes the yeast to die.  The alcohol builds up and
kills the yeast.  Since the alcohol is volatile, that's why it smells
differently.  I also suspect the alcohol is also why the CO2 doesn't mix
as easily, although I have no scientific basis for that statment other
than your observations.
