Practice questions on Toxic Responses
Allergic reactions differ from typical toxic responses because
- They follow standard dose-response assumptions
- They result from immune system stimulation releasing natural chemicals
- They result from the chemical directly acting on cells
- They only occur at high doses
Answer: B. Allergic reactions are immune-mediated responses where the chemical stimulates the body to release natural mediators (histamine, leukotrienes, etc.) that cause the observed effects. Unlike toxic responses, allergic reactions don't always comply with dose-response assumptions and can occur at very low doses in sensitized individuals.
