C.violifer hemoglobin has a lower P50
P50 represents the oxygen tension when hemoglobin is 50% saturated with oxygen
Vertebrate species native to higher altitudes have a lower P50 than their lowland counterparts. This adaptation facilitates uptake of O2 from hypoxic environment prevalent at higher altitudes.
As a result of lower P50, the Hb-O2 affinity decreases and more oxygen is dissociated from the hemoglobin and is available for uptake by the tissue.

A. . Hyperpnea would result in ___________________________ within the blood. an increase in both Pressure (oxygen) and Pressure (carbon dioxide) 2. Decreased Pressure (carbon dioxide) results in an increase in blood pH levels. Both of these conditions result in a shift of the oxygen-hemoglobin dissociation curve to the ______________________. This shift _______________ hemoglobin’s affinity for oxygen. select 3. Increased levels of 2,3 BPG occur in response to decreased blood pH levels. With all other variables unchanged, an increased concentration of...

The partial pressure of oxygen in the lung alveoli is a bit lower than in ambient...
The partial pressure of oxygen in the lung alveoli is a bit lower than in ambient air, being about 100 mm of mercury, or 0.13 Atm (it is lower than the partial pressure in air mainly because oxygen is continually taken up by the alveolar capillaries and carbon dioxide is continually released into the alveoli). In cell-free blood plasma (or a saline solution formulated to match key characteristics of blood plasma), which lacks red blood cells and therefore lacks hemoglobin,...

Aviation and high-altitude physiology is a specialty in the study of medicine. Let x = partial pressure of oxygen in the alveoli (air cells in the lungs) when breathing naturally available air. Let y = partial pressure when breathing pure oxygen. The (x, y) data pairs correspond to elevations from 10,000 feet to 30,000 feet in 5000 foot intervals for a random sample of volunteers. Although the medical data were collected using airplanes, they apply equally well to Mt. Everest...

Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...
