CAM help

    I have some personal confusion regarding the adaptiveness of CAM 
photosynthesis.  It is usually portrayed as a pathway that decreases 
photorespiration, and, as such, it is presented an alternative to C-4 
photosynthesis.  To decrease photorespiration, there should be a mechanism to 
decrease [oxygen] in the region of the chloroplasts.  I don't see that.  It 
appears to me that the primary purpose of CAM is water conservation.  

    Am I missing something here?
