Answer #1

Answer : The llama hemoglobin has a higher affinity for O2 than human hemoglobin

Llama hemoglobin would be advantageous at high altitudes because it can become 100 percent saturated at the low PO2 of the high-altitude environment. Therefore the hemoglobin can carry a full load of O2 to the tissues

The total atmospheric pressure at higher altitude decreases relative to sea level (760mmHg). As a result, the partial pressure of oxygen decreases at higher altitude. This decreases the partial pressure differences between air breathing organisms, which limits oxygen intake at higher altitudes relative to sea level. Higher altitude does changes the percent of oxygen in air, which is 21%.

Which of the following would happen to the O2 saturation curve of Hemoglobin in the presence of normal amounts of 2, 3 DPG if  a drug  were administered that prevents the binding of the 2,3 DPG to Hemoglobin: The curve would be shifted to the right from that of normal red cells. The concentration of O2 necessary to saturate Hb would be higher than the normally required O2 binding at high PO2 would be greatly decreased The amount of O2 delivered to...

You are studying a newly discovered species of Arabidopsis native to Greenland. When you isolated this organism in the field, temperatures were mild (average high of 40 F) but the day length (as measured by sunlight) was approaching 18 hours. Would you have observed flowers? Why or why not? (Limit your response to 2 sentences.) Compare and contrast combinatorial control of whorl identity in flower development and combinatorial control of cell identity in induced pluripotent stem cells. (Maximum 3 sentences.)

You are researching what you are hoping is a new rare native plant species found in a newly-restored habitat. You are anxious to understand what kind of plant it is and help it become established and grow well. Your colleague shares her observations: the plant has a sizeable taproot, leaves with branched veins, and flowers with five petals. When transplanting to a new location, you notice that some of the plants have knobby growths on the roots. The plants with...

A hypothetical mutant receptor binds poorly to the 5-HT3 neurotransmitter, but has normal gating properties. (For instance, when exposed to an artificial agonist that has very high affinity for the receptor, the channel displays a current trace similar to that seen in Figure 3, top left.) Would you expect this mutant receptor to have an EC50 value higher or lower than 1 μM? Would you expect the ∆∆G (EC50) for this mutant receptor to be positive or negative? How about...
