KROK 1 Stomatology 2012 – Question 37 · KROK (Dentistry)
A 34-year-old patient has low endurance of physical loads. At the same time skeletal muscles have increased concentration of glycogen. This is caused by the reduced activity of the following enzyme:
- A. Glucose-6-phosphatase
- B. Glucose-6-phosphate dehydrogenase
- C. Phosphofructokinase
- D. Glycogen phosphorylase
- E. Glycogen synthase
Hint
Ask which enzyme is needed to release glucose units from muscle glycogen during exercise; if it fails, glycogen accumulates and energy supply drops.
