Question

As a graduate teaching assistant for your physiology class, you are required to provide an evaluation of the following examples of student work with Boyle's law. No two answers can have the same grade assigned. Hemoglobin is sensitive to the concentrations of a number of local markers of metabolism that alter its affinity for oxygen resulting in greater oxygen offloading at metabolically active systemic capillaries. For instance, tissue elevations in a metabolite of glycolysis (DPG), H+, and temperature all decrease hemoglobin's affinity for O2 and result in greater oxygen delivery to meet demand. The affinity and saturation of hemoglobin is largely influenced via competitive binding due to a number of conditions indicating a higher tissue production of carbon dioxide. Active tissues will see increases in temperature, pH, and DPG (a glycolysis metabolite) that collectively increase oxygen affinity resulting in a greater partial pressure of oxygen in the arterial blood. During times of heightened metabolic activity, elevations of temperature, acidity, and DPG (a glycolytic metabolite) allosterically alter the binding affinity of hemoglobin to oxygen. This results in increased affinity at partial pressures of O2 seen in the systemic capillaries and decreased oxygen offloading to actively respiring tissues. Grade Earned: A During times of heightened metabolic activity, elevations of temperature, acidity, and DPG (a glycolytic metabolite) allosterically alter the binding affinity of hemoglobin to oxygen. This results in increased affinity at partial pressures of O2 seen in the systemic capillaries and decreased oxygen offloading to actively respiring tissues. C The affinity and saturation of hemoglobin is largely influenced via competitive binding due to a number of conditions indicating a higher tissue production of carbon dioxide. Active tissues will see increases in temperature, pH, and DPG (a glycolysis metabolite) that collectively increase oxygen affinity resulting in a greater partial pressure of oxygen in the arterial blood.

For instance, tissue elevations in a metabolite of glycolysis (DPG), H+, and temperature all decrease hemoglobin's affinity for O2 and result in greater oxygen delivery to meet demand.
