KROK 1 2011 – Question 9 · KROK (Medicine) · Biological Chemistry
Researchers isolated 5 isoenzymic forms of lactate dehydrogenase from the human blood serum and studied their properties. What property indicates that the isoenzymic forms were isolated from the same enzyme?
- A. The same physicochemical properties
- B. Tissue localization
- C. The same molecular weight
- D. Catalyzation of the same reaction
- E. The same electrophoretic mobility
Hint
Ask what defines an enzyme functionally, so that molecular forms differing in charge, size and tissue origin still count as one enzyme.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
