The conversion of arachidonic acid to prostaglandins involves the action of:

Arachidonic acid is an essential fatty acid that is present in cell membranes and can be converted into various important compounds, including prostaglandins. These compounds have a variety of roles in the body, such as regulating inflammation, blood clotting, and smooth muscle contraction. The conversion of arachidonic acid to prostaglandins is catalyzed by the enzyme cyclooxygenase. Lipoxygenase is another enzyme that is involved in the conversion of arachidonic acid, but it produces different compounds called leukotrienes. Hydrolase and isomerase are not involved in the conversion of arachidonic acid to prostaglandins, making them incorrect choices.
