BIOS 242 exam 3 UPDATED ACTUAL Questions and CORRECT
Answers
Question: Botulism
Correct Answer: Prevents the release of acetylcholine, resulting in flaccid paralysis. It is an endotoxin.
Produced by Clostridium botulinium. Used by doctors for Botox.
Question: Tetanus (tetanospasmin toxin)
Correct Answer: Bind to peripheral motor neurons, blocking inhibition of muscle contractions. It is a
neurotoxin. Produced by C. tetani. Death results from respiratory arrest.
Question: Stages of bacterial phagocytosis
Correct Answer: 1. Chemotaxis 2. Phagocytic cell PRRs recognize and bind PAMPs 3. Engulfment 4.
Phagosome formation 5. Phagolysosome forms 6. Killing of bacterial cell 7. Debris release
Question: bacterial phagocytosis
Correct Answer: Phagocytes (macrophages and neutrophils) engulf and destroy bacteria to protect the
body from infection.
Question: chemotaxis
Correct Answer: Phagocytes move to the site of injury.
Question: Stage 2
Correct Answer: Phagocytic Cell PRRs Recognize and Bind Microbial PAMPs
Question: Engulfment
Correct Answer: phagocyte engulfs microbe
Question: Phagosome formation
Correct Answer: The microbe is surrounded with a sac called the phagosome
Question: phagolysosome formation
Correct Answer: phagosome fuses with lysosome
Question: killing of bacterial cell
Correct Answer: Releases enzymes after fully enclosing the bacteria to kill the it.
Question: Debris release
Correct Answer: Some of the debris is released, the rest is shown to the t cells t form anitbodies.
Question: Passive immunity
Correct Answer: Passive immunity occurs when an individual receives immune products from another
organism.
Question: passive artificial immunity
Correct Answer: injection of antibodies
Question: passive natrual immunity
