Tissues having higher metabolic rate demand more oxygenMostly active tissues like muscles rapidly use oxygen forproduction of ATP thus partial pressure of oxygen is reduced to20mm Hg The partial pressurepp of O2 inside capillaries isnearly100 mm Hg the difference in partial pressure becomes highhence oxygen dissociates from Hb and releases to tissuesThe reverse occurs in case of adipose having low metabolicrates less oxygen is used by adipose cells the pp of oxygenremains high results in less oxygen molecules to dissociate    See Answer
