    Whenever I see this image I always wonder 2 things:

    1. What makes hemoglobin more efficient?
    2. Why do we even need these fancy molecules to transport oxygen? Can’t we produce some kind of biological ampule that holds some pure O2 for consumption by the various processes that need it? We have dedicated organelle structures for similar tasks (i.e. mitochondria)
