Which of the following enzymes breaks down arachidonic acid into prostaglandins?
a. phospholipase

d. Any slight trauma to a nerve fiber stimulates an enzyme called phospholipase A2, which breaks off arachidonic acid from the phospholipids bound in the cell membrane. Arachidonic acid enters two metabolic pathways: In the first pathway, an enzyme called cyclooxygenase breaks down (metabolizes) arachidonic acid into prostaglandins (PGE2) and prostacyclin (PGI2) and thromboxane A2.
