Transport of Respiratory Gases by Blood : Oxygen Transport : since oxygen is poorly soluble in water, most (> 98%) of oxygen transported by blood is bound to hemoglobin - : hemoglobin with bound oxygen is oxyhemoglobin (HbO 2 ); hemoglobin without bound oxygen is reduced hemoglobin or deoxyhemoglobin (HHb) o cooperation: each hemoglobin can bind 4 oxygen molecules; after first oxygen is bound, binding of other 3 is facilitated o hemoglobin with 4 oxygens bound is fully saturated with oxygen o the oxygen-hemoglobin dissociation curve shows that hemoglobin is almost completely saturated with oxygen at Po 2 of 70 mm Hg Kevin Kelleher, MTC Biology 211 Study Notes Exam 2 20 2 > 104 mm Hg, oxygen is still available for tissues 2 in general will decrease hemoglobin
