A bound system is typically at a lower energy level than its unbound constituents because its mass must be less than the total mass of its unbound constituents. For systems with low binding energies, this "lost" mass after binding may be fractionally small, whereas for systems with high binding energies, the missing mass may be an easily measurable fraction. This missing mass may be lost during the process of binding as energy in the form of heat or light, with the removed en… WebThe idealized PES spectrum of lithium. The spectrum shows two peaks, one with a binding energy between 10 and 1 MJ/mol and another with a binding energy between 1 and 0 MJ/mol. The peak with the higher binding energy is twice as intense as the peak with the lower binding energy.

WebLike you said, CO2 can bind to the hemoglobin subunit causing a conformational change of the protein decreasing O2 affinity for the molecule; this is known as allosteric inhibition. ALSO CO2 can react with H2O eventually leading to the creation of HCO3- and H+, the H+ protons will reduce the pH of the environment which lowers Hb's affinity for O2.
