Question

Which of the following has arachidonic acid as a precursor?

• A. Prostaglandins
• B. Leukotriens
• C. Gastric inhibitory peptide
• D. Both A and B

Answer 1

The correct option is D Both A and B

Prostaglandins and leukotrienes are commonly known as eicosanoids. These molecules are produced by the oxidation of the arachidonic acid. The prostaglandins are released by the damaged cells. The release of these molecules causes fever and pain. Leukotrienes are released by the immune cells which communicate with the other cells to release molecules which cause redness, itching, swelling, etc.

Thus, the correct answer is option D.
