KROK 1 2009 – Question 165 · KROK (Medicine) · Biological Chemistry
A newborn develops dyspepsia after the milk feeding. When the milk is substituted by the glucose solution the dyspepsia symptoms disappear. The newborn has the subnormal activity of the following enzyme:
- A. Invertase
- B. Isomaltase
- C. Amylase
- D. Maltase
- E. Lactase
Hint
Glucose is absorbed without digestion, so ask which milk disaccharide must be split first and by which enzyme of the small-intestinal brush border.
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.
