Hemoglobin O₂ binding affinity decreases under what conditions: - Bohr Effect Low pH (High CO₂ and high H⁺)=> oxygen loads released by hemoglobin if do opposite (decrease CO₂ or H⁺)=> increase affinity for oxygen Haldane Effect - if you increase the pressure of CO₂=> increase CO₂ content in blood. * oxygenation of blood in the lungs displaces CO₂ from hemoglobin=> increase CO₂ removal *Hemoglobin without O₂ acts as blood buffer by accepting H⁺... this will...

4.1: ATOMIC STRUCTURE Earlier in this course, we explored a very elementary view of atomic structure. We learned about protons, neutrons, and electrons (the three elementary particles that comprise an atom) and their properties. In this module, we will study these particles in detail and learn how their presence and arrangement determines the properties of all matter. The Electron During the 1800s, a number of scientists, including Sir Humphrey Davy, Michael Faraday, R. A. Milligan, G. J...
