The hemoglobin, for crocodiles, why does it prefer T state if it wants to hold breath for a longer period of time? I thought it would want to prefer R state if it wants to hold onto the oxygen.
furthermore, how is T state harder to bind O2, but also harder to release O2?
I thought T state is easier to release O2.
I thought R state was closer to Myoglobin curve, not T state.
