← Human Body & HealthA researcher introduces a compound that inhibits phospholipase A2 into a cell culture stimulated with lipopolysaccharide (LPS). Which consequence follows regarding inflammation?
A)Increased leukotriene production occurs
B)Prostaglandin synthesis will be suppressed✓
C)TNF-α production will experience surge
D)Neutrophil chemotaxis gets amplified
💡 Explanation
Phospholipase A2 is required to release arachidonic acid from membrane phospholipids, a necessary precursor for prostaglandin synthesis. Therefore, inhibiting phospholipase A2 suppresses prostaglandin production because the substrate is unavailable, rather than enhancing leukotriene or TNF-α production which use different pathways.
