Explain how acute exercise would challenge the delivery ofoxygen and release of carbon dioxide as well as how acute exercisemay actually enhance the delivery and release of oxygen at thetissues via an explanation of shifting of the oxyhemoglobindissociation curve, etc. Make sure to include informationabout hemoglobin and myoglobin structure and a full explanation ofthe sigmoidal shape of the dissociation curve (i.e. loading andunloading portions).

FACTORS AFFECTING THE DISSOCIATION CURVEThe strength with which oxygen binds to hemoglobin is affectedby several factors These factors shift or reshape theoxyhemoglobin dissociation curve A rightward shift indicates thatthe hemoglobin under study has a decreased affinity for oxygenThis makes it more difficult for hemoglobin to bind to oxygenrequiring a higher partial pressure of oxygen to achieve the sameoxygen saturation but it makes it easier for the hemoglobin torelease oxygen bound to it The effect of this rightward shift ofthe curve increases the partial pressure of oxygen in the See Answer
