Leukotrienes are a group of inflammatory mediators derived from arachidonic acid. This conversion is facilitated by the enzyme lipoxygenase, which is responsible for the production of leukotrienes. Cyclooxygenase, isomerase, and hydrolase are not involved in this specific process and therefore are incorrect choices. Cyclooxygenase is responsible for the production of prostaglandins, while isomerase and hydrolase have other roles in biochemical reactions. Therefore, the correct answer is C.
