Hemoglobin oxygen affinity lab test
WebCarboxyhemoglobin is produced by the binding of carbon monoxide (CO) to hemoglobin. CO is generated during incomplete combustion of organic products and has toxic effect because it competes with oxygen for the same binding site in the Fe2+ of Hb. Hemoglobin bound to CO is unable to transport O 2. Hb has a 210-fold greater affinity for carbon ...

WebDescribe the Bohr effect. Cells that are active and need oxygen produce CO₂ as a byproduct. This CO₂ combines with water to form H+ and HCO₃- which increases the acidity around the cell. This increase in acidity (decrease in pH) results in the lowering in affinity of hemoglobin for O₂ which causes hemoglobin to release its oxygen to ...
