The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 27-year-old male suddenly develops severe abdominal cramping and bloody diarrhea. The patient reports consuming undercooked ground beef four days prior to the onset of the symptoms. Which of the following best describes the toxin-mediated mechanism of this disease process?   (A) Depolymerization of actin filaments in gastrointestinal mucosal cells, leading to mucosal cell death   (B) Increased pH of gastrointestinal lumen resulting in reduced mucosal absorption   (C) Increased intracellular cAMP in gastrointestinal mucosal cells, resulting in decreased absorption and increased secretion in the digestive tract   (D) Inhibition of the 60S ribosomal subunit, resulting in decreased protein synthesis in gastrointestinal mucosal cells
