Webb13 nov. 2024 · Oxygen Delivery at Tissues. As shown on the diagram above, the percentage of oxygen bound to haemoglobin is related to the partial pressure of oxygen (pO 2) at a given site.When oxyhaemoglobin reaches a tissue with a low pO 2 (e.g. skeletal muscle), it will dissociate into oxygen and haemoglobin, resulting in an increase in local pO 2.When … WebbFigure 16-15 Potential energy diagrams showing the effect of a catalyst. The catalyst provides a different mechanism, corresponding to a lower-energy pathway, for the formation of the products. A catalyzed reaction typically occurs in several steps, each with its own barrier, but the overall energy barrier for the net reaction,, is lower than ...
