Document Summary

5. 3 role of anaerobic and aerobic metabolism in exercise. 5. 4 oxidative phosphorylation in the formation of atp. 5. 11 diseases that result from abnormal mitochondrial or peroxisomal function. To satisfy cellular oxygen demand, our blood runs red with hemoglobin, which binds to oxygen and carry it to all portions of our body. Much of human anatomy and physiology is devoted to insuring an adequate supply of oxygen. Providing enough oxygen is a preoccupation of anesthesiologists, astronauts, scuba divers, athletes . Later on, hydrolysis of atp helps the cell perform different works. Molecular oxygen (o2) can be a very toxic substance, taking on extra electrons and reacting with a biological molecule: recall: o2. - +2h+ h2o2 + o2: consequently, species including humans must possess metabolic pathway to utilize. Organisms that incorporate o2 into their metabolism can oxidize foodstuff to co2 and h2o and extract a large amount of their energy content: these organisms are oxygen-dependent (aerobes).
