Solution
The most likely explanations for the different responses that Catalina had compared to Daisy on arriving at high altitude are:
-
Altered mitochondria energetics: People who live at high altitudes may have adaptations in their mitochondria, the energy-producing structures in cells, that allow them to use oxygen more efficiently.
-
Genetics variance: Genetic differences could also play a role. Some populations have lived at high altitudes for thousands of years and may have evolved genetic adaptations to the low-oxygen environment.
-
Higher hematocrit levels: Hematocrit is the proportion of your blood that is made up of red blood cells. Red blood cells carry oxygen, so having a higher hematocrit level can help your body get the oxygen it needs in a low-oxygen environment. People who live at high altitudes often have higher hematocrit levels than people who live at sea level.
Increased anaerobic metabolism capacities is not a likely explanation. Anaerobic metabolism is the creation of energy through the combustion of carbohydrates in the absence of oxygen. This occurs when your lungs cannot put enough oxygen into the bloodstream to keep up with the demands of your muscles for energy. It is not a sustainable way of producing energy and is not likely to be a long-term adaptation to living at high altitudes.

his scenario applies for the next few questions:Daisy has lived in Melbourne all her life, but an amazing opportunity came up and she has the opportunity to move to Le Paz in Bolivia for her research. She jumped at the opportunity and arrived at La Paz which is located at 3,640 metres above sea level. On arriving at La Paz, she felt tired and a little ill and initially thought that it was the fatigue from the journey. Her energy returned over the next few days and she was able to start her research project.Which one of the following response would you NOT expect to see during Daisy’s first few days at La Paz?.Group of answer choicesIncrease contraction of the spleen to increase blood volumeHyperventilation resulting in alkalosisHyperventilation resulting in hypercapniaHyperventilation due to hypoxia
Sally, who lives mostly in Frankston travelled to La Paz in Bolivia (altitude 3625 m). They experienced shortness of breath. This is because their hemoglobin: choosing from below Binds oxygen more tightly in the lungs than a local. Binds oxygen more weakly in the lungs than a local. Binds oxygen more weakly in the tissues than a local. Binds oxygen more tightly in the tissues than a local.
