One important regulation point in the aerobic respiration of mammals occurs in glycolysis at the site of the enzyme phosphofructokinase, which is: A) inhibited by high levels of ATP. B) inhibited by low levels of ATP. C) inhibited by high levels of AMP. D) activated by the presence of O₂. E) activated by the introduction of glucose.
