Lecture 8 - Biotransformation
See Lecture Schedule for
Delivery Date
Learning Objectives
- Explain the role of biotransformation in toxicokinetics.
- Describe how biotransformation facilitates the
elimination of toxicants or their metabolites from the body.
- Distinguish between Phase I and Phase II
biotransformation reactions.
- Define bioactivation or toxication.
- Identify the tissues responsible for biotransformation
reactions.
- List the factors affecting biotransformation in humans.
- Summarize the role of elimination in toxicokinetics.
- Describe processes occurring in the kidney, liver, and
lung as related to the elimination of toxicants.
