4. D. amylase<br />Amylase is the enzyme that breaks down starch in the first stage of catabolism.<br /><br />5. C. intermembrane space of mitochondria<br />The reactions catalyzed by the pyruvate dehydrogenase complex occur in the intermembrane space of mitochondria.<br /><br />6. E. TPP, CoA-SH, FAD, lipoic acid, NAD<br />Coenzymes participate in the reaction of oxidative decarboxylation of α-ketoglutarate in the following sequence: TPP, CoA-SH, FAD, lipoic acid, NAD.<br /><br />7. D. α-ketoglutarate → succinyl-CoA<br />The multienzyme complex catalyzes the conversion reaction of α-ketoglutarate to succinyl-CoA.<br /><br />8. B. arachidonic acid<br />The substrate of microsomal oxidation is arachidonic acid.<br /><br />9. B. a3<br />The cytochrome located on the inner membrane of mitochondria outside the enzyme complexes is a3.<br /><br />10. A. a relatively high content of components of the respiratory chain and a small amount of H+-ATPases<br />Mitochondria of brown fat cells differ from the mitochondria of other cells in that they contain a relatively high content of components of the respiratory chain and a small amount of H+-ATPases.<br /><br />11. A. lactase<br />Eating confectionery and sweet tea is accompanied by dyspeptic disorders in a child, such as vomiting and diarrhea. Milk does not cause such a reaction because of the deficiency of the enzyme lactase.<br /><br />12. B. phosphofructokinase<br />Iodoacetate, an inhibitor of sulfhydryl groups, suppresses glycolysis at the level of the enzyme phosphofructokinase.<br /><br />13. B. 2-phosphoglycerate → phosphoenolpyruvate<br />The redox reaction in glycolysis is the conversion of 2-phosphoglycerate to phosphoenolpyruvate.
