The death cap mushroom (Amanita phalloides) is considered one of the world's deadliest mushrooms. The toxicity of the Amanita species is due to the presence of two groups of toxins known as amatoxins and phallotoxins, both made of multiple cyclic peptide chains (circular sequences of bonds). Do some research about the death cap and answer: What makes the Amanita phalloides toxins so harmful that even one cap can kill an adult? Hint: Your short answer should be related to the processes involved in protein synthesis. (Keep your answer short, around 90 words).

Amanita virosa (a) is the mushroom commonly cultivated for food (b) is the yeast that ferments wine and beer (c) produces the unique flavor of many cheeses (d) is a highly toxic mushroom (e) has been ingested for its hallucinogenic properties
TOPIC 1: What is the function of the highlighted structure in the picture below? Select one: It lifts the cap and the gills above the ground, allowing the spores to be scattered by the wind. It protects the other organs from the rain. It produces the spores. It decomposes dead organic materials and transports the released nutrients to all the mushroom's organs.

People who ingest A. phalloides (the source of α-amanitin) initially experience gastrointestinal distress caused by other toxins also produced by this mushroom. α-Amanitin shuts down the action of RNA polymerase II, but death does not occur until about 48 hours after ingestion and usually involves liver dysfunction. Suggest a reason for the delay in lethality.
