9 week exam question 25

9 week exam question 26

Today’s Objective: Objective: Introduction to biochemistry and organic compounds

Dehydration Synthesis Demonstration

Quick Review & Some New Information Monomers are small single subunits or building blocks that form polymers. Examples of monomers and polymers include: 1. amino acids are the monomers for proteins/polypeptides 2. nucleotides are the monomers for nucleic acids (RNA/DNA) Monomers are joined together to form polymers by a chemical reaction called Dehydration Synthesis or also known as a Condensation Reaction. Polymers are broken down into their monomers (digestion) by a reaction called Hydrolysis *Water is the important link in both reactions!!! 8

Biochemistry Introduction ppt Day 1 So far this year we’ve learned about: Ecosystems, Communities, Populations, and Individual Species/Organisms We’ve learned all about the cells (Prokaryote vs. Eukaryote and Eukaryotic Plant Cells vs. Eukaryotic Animal Cells),. The question now is……what makes up the cell????? 9

Exit Ticket 1. Please compare and contrast hydrolysis and dehydration synthesis. 2. Carbohydrates are one of the four biologic macromolecules(biomolecules). They are a polymer. What monomer are they made from?

Oral Conclusion Please describe the base pairing rules of DNA and of RNA Describe the structure of DNA 3. How are RNA and DNA different? 4. Describe DNA Replication. 5. Describe Transcription 6. Describe Translation 7. Describe a mutation 8. Describe a Frame Shift Mutation

Oral Conclusion Please give an example of a limiting factor Describe one way humans are impacting the nitrogen cycle Describe one way humans are impacting the carbon cycle How are microorganisms such as bacteria beneficial to an ecosystem? Organism? Give an example of a producer. A consumer Describe biological magnification. Give an example of an abiotic factor. A biotic factor. Describe an invasive species and give an example. Why does only 10% of the energy move from trophic level to trophic level? How is primary succession different from secondary succession? Compare and contrast natural and artificial selection. Give an example of evolution. Describe two – evidence of evolution. Compare and contrast natural and artificial selection Compare and contrast eukaryotic and prokaryotic cells How are plant and animal cells different?
