061 The Bohr Effect

In this episode, Leslie Samuel explains the Bohr Effect, focusing on how carbon dioxide and pH levels influence hemoglobin's affinity for oxygen. The video reviews the oxygen dissociation curve and discusses how exercise and cellular respiration affect oxygen release. The formation of carbamate and its role in stabilizing deoxygenated hemoglobin is also covered. The episode concludes with resources for further learning.
