Answer to Question #54736 in Other Biology for Jasmine
Explain why the level of oxygen increases as the level of exercise increase. (3marks)
During physical exercises, organism’s requirement of oxygen extremely increases. Oxygen is needed to provide muscles with energy, produced by mitochondria. Actually, at the outset, the level of oxygen decreases and the level of CO2 increases. That causes the pH lowering (the amount of H+ increases) of the blood, in other words, acidification. Our respiratory center, which is localized in the brainstem, becomes activated by detecting of H+ increasing and we start breathing faster and more deeply. As the result, blood is enriched by oxygen and its level increases.
The assignments were completed in a timely manner and were complete. I missed a few points on small little nit pick things that my professor didn't like but I still got a rocking grade and was very satisfied! The price and time was what kept me coming back for more assignments! Thanks so much!
