Document Summary
Two key concepts: haldane effect: o2 loading facilitates carbon dioxide unloading (from hemoglobin, bohr effect: carbon dioxide loading (through hydrogen formation) facilitates o2 unloading (from haemoglobin) High altitude physiology: air = less compressed (thinner/ less dense, a given volume of air contains fewer molecules = less available oxygen. Therefore, you have to breathe faster and deeper to get oxygen into your body. Distributing prohibited | downloaded by arsen terzian (arsen98@gmail. com) lomoar cpsd|2151316: results in lower than normal hemoglobin saturation levels because less o2 is available to be loaded. Increase in breathing and heart rate oxygen to the cells. Deep sea driving: a tmosphericp ressure changes, nitrogen narcosis, oxygen posioning, carbon dioxide toxicity, hyperbaric chambers. Question 7: (also see points from adrianne on fb chat) There are three stages of respiration: glycolysis, the krebs cycle, and the electron transport chain (etc). In glycolysis oxygen is need to convert glucose (through many processes) into pyruvate which is utilzed in the krebs cycle.
