Dinophysis produces which toxin?

Explanation:
Dinophysis produces okadaic acid, which leads to diarrhetic shellfish poisoning. Okadaic acid is a toxin that inhibits intestinal protein phosphatases, causing increased cellular phosphorylation and fluid secretion in the gut, resulting in diarrhea and abdominal cramps. It is heat-stable, can accumulate in shellfish, and symptoms typically appear within hours after ingestion. The other toxins listed come from different organisms and cause distinct syndromes: domoic acid is linked to amnesic shellfish poisoning with memory and neurological effects; saxitoxin causes paralytic shellfish poisoning by blocking sodium channels; tetrodotoxin also blocks sodium channels and is associated with pufferfish toxicity.
