Define ecological biochemistry. • Explain biochemical adaptation and the roles of secondary compounds. • Describe detoxification and the primary metabolic pathways in plants and animals. • Explain the key processes and factors involved in biotransformation & biodegradation. • Explain the concepts of sequestration, bioaccumulation, and biomagnification. • Contrast different forms of ecological biochemical interaction. | Ecological Biochemistry Principles of Environmental Toxicology Instructor Gregory Möller . University of Idaho Principles of Environmental Toxicology Learning Objectives Define ecological biochemistry. Explain biochemical adaptation and the roles of secondary compounds. Describe detoxification and the primary metabolic pathways in plants and animals. Explain the key processes and factors involved in biotransformation biodegradation. Explain the concepts of sequestration bioaccumulation and biomagnification. Contrast different forms of ecological biochemical interaction. 2 Principles of Environmental Toxicology Ecological Biochemistry Coupling of the observational science of ecology with the molecular science of biochemistry. Ecological interaction. Principles of Environmental Toxicology Ecological Biochemistry 2 Synthesis and transformation of chemicals in the environment as the result of biochemical processes in an organism to aid in species survival. Includes 1. Biochemical adaptation. Biosynthesis. 2. Detoxification. Biodegradation biomineralization. 3. Bioaccumulation biomagnification. 4 4. Ecological biochemical interaction. Principles of Environmental Toxicology Biochemical Adaptation The metabolic flexibility of a living organism to fit into a changing environment improving chances for survival and reproduction. - Evolution Many generations. - Acclimatization. Lifetime of an individual. Challenge decipher the strategy of the natural world. - Example THC 5 Harborne Principles of Environmental Toxicology Competitive Symbiotic Interactions Plant Plant Animal. - Secondary plant compounds. Animal Animal. - Venoms toxins. 6 1 Principles of Environmental Toxicology Toxins and Survival Strategy Organisms often synthesize or use toxins in their survival strategy. - The most conspicuous non-event in the history of the angiosperms is the failure of insects and other herbivores to attack plants on a wide-scale.
