KROK 1 2021 – Question 21 · KROK (Medicine) · Biological Chemistry
Synovial fluid is known to reduce the friction between articular surfaces. In rheumatism or arthritis, its viscosity decreases because of depolymerization (destruction) of the following substance:
- A. Hyaluronic acid
- B. Albumin
- C. Heparin
- D. Glycogen
- E. Collagen
Hint
Consider which listed substance is a long, hydrated polymer dissolved in synovial fluid that gives it viscosity and is degraded by free radicals and lytic enzymes in inflamed joints.
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.
