Utilization of arachidonic acid via cyclooxigenase pathway results in formation of some bioactive substances. Name them:
- A. Thyroxine
- B. Biogenic amins
- C. Insulin-like growth factors
- D. Somatomedins
- E. Prostaglandins
Hint
Consider what cyclooxygenase makes from this 20-carbon fatty acid: local lipid mediators of inflammation, pain, fever and platelet aggregation, not hormones built from amino acids.
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.
