2.  Tested corn & milk for macromolecules  Cow used macromolecules in its food to create new macromolecules  Food provides energy & raw materials for growth

3.  Blocks  You broke down & reassembled proteins in a chain from plants to cows to humans  Your hands were enzymes  One handed (lower concentration) was slower  Non dominant hand (denatured) was the slowest

4.  Tested milk for glucose  Observed how lactase breaks down lactose to produced glucose  Enzymes can be used to break down or build macromolecules

5.  Energy Diagrams  Heat of reaction  Activation energy  Reactants  Products

6.  Looked at the effects of variables on enzyme function  Enzyme/ substrate concentration  pH  temperature

7.  Polymer/ monomer  Carbohydrates/ simple sugars (glucose)  Lipids/ fatty acids  Proteins/ amino acids  Nucleic acids/ nucleotides  Functions

8.  Substrate  Active site  Specificity  Not used up/ reusable  Biological catalysts  Speed chemical reactions  Reduce activation energy

9.  Decomposition  Hydrolysis  Synthesis  Dehydration synthesis
