Intro to Enzymes correct answers - a requirement for life is the ability to efficiently and selectively catalyze chemical reactions - most biomolecules are very stable and the uncatalyzed transformations would be too slow to permit life - experiments done showed that dead yeast could still convert sugars into alcohol indicated that the reactions of life could be separated from life - there was a factor in yeast catalyzing the reaction vitalism correct answers a belief that originally, bioc...

A good transition-state analog: A) binds covalently to the enzyme. B) binds to the enzyme more tightly than the substrate. C) binds very weakly to the enzyme. D) is too unstable to isolate. E) must be almost identical to the substrate. - Answer-binds to the enzyme more tightly than the substrate. A major advance in the application of mass spectrometry to macromolecules came with the development of techniques to overcome which of the following problems? A) Macromolecules were insoluble i...

UNE Medical Biochemistry Midterm Review Already Graded A A family presents for genetic counseling. The couple has two female children who are alive and well; however, their infant son recently died in the nursery with severe hemolysis (lysis of red blood cells) and jaundice. The wife recalls she lost a brother in infancy with severe hemolysis, induced after a viral infection. The physician suspects a glucose-6-phosphate dehydrogenase deficiency, this would result in a deficiency in which of the...
