The mammalian kidney can produce acidic or alkaline urine dependent upon physiological conditions.  In class we discussed H+ secretion using a Na+/H+ antiporter, coupled with a HCO3- facilitated transport mechanism. 
a.   Using a different mechanism than discussed in class, how can net H+ be secreted?  Be sure to maintain electrochemical neutrality within the cell and show the origin of ions moved.  Is this an adaptive mechanism?
b.   If you reversed the orientation of the Integral Membrane Proteins used in part a., what would the effect be on the organism?  Could this be adaptive?


im trying to think of another thing...but I really dont know. Are there any other mechanisms that can secrete H+?
