Shifting of the O2 dissociation curve to the left will produce ... what ?

  #2

This is how I remember it:
...Exercising Muscles do the Right thing: they shift the curve to the Right
and everything increases (Temperature: 2,3DPG : P CO2 ) except the pH.
....CO and HbF don't do the right thing: they shift to Left and Lower everything except the pH .
Basically Kaplan.

Absolutely correct.But how will shifting of the curve to the left affect affinity for o2.

  #4

When you have affinity for something, you keep it.
Shifting to the left, increases the affinity for O2, reduces delivering of O2 to tissues.
