1) Anemia, hemorrhage, and chronic obstructive pulmonary disease can all cause metabolic acidosis. The best explanation is that the lack of oxygen causes: A) a decrease in insulin that, in turn, increases anaerobic glycolysis in the brain B) a decrease in oxidative phosphorylation so the cells have to rely upon anaerobic glycolysis C) a decrease in the oxidation of tyrosine to epinephrine which decreases gluconeogenesis in muscle D) a decrease in the removal of CO2 from the blood. The resulting decrease in pH causes an increase in glycolysis in most cells E) an increase in glycolysis in red blood cells
