Q1
A physiologist models oxygen binding to hemoglobin in a capillary bed. She notes that in metabolically active tissue, local pH decreases and temperature increases. Assume hemoglobin exhibits cooperative binding and that oxygen unloading depends on both binding affinity and the partial pressure gradient. Based on the described relationship between pH (Bohr effect) and binding equilibria, which outcome would most likely result in the active tissue?
