| Term/Question | Definition/Answer |
| Why is carbon a building block? | Because it can bond with 4 other molecules |
| 4 types of macro-molecules | Lipids, Proteins, Carbohydrates, and Nucleic Acids |
| examples of a carbohydrate | glucose, cellulose, and starch |
| examples of a lipid | fats, waxes, oils, and cutin |
| examples of a protein | enzymes, hormones, antibodies, and callegen |
| examples of nucleic acid | DNA & RNA |
| monomer of a carbohydrate | saccharide |
| monomer of a lipid | phospholipid |
| monomer of a protein | amino acid |
| monomer of nucleic acid | nucleotide |
| function of a carbohydrate | "easy energy" |
| function of a lipid | long term energy |
| function of a protein | "build and bind" |
| function of nucleic acid | produce protein |
| A phospholipid is made of... | glycerol and fatty acids |
| A nucleotide is made of... | phosphate, sugar, and a base |
| Amino acids strands are made of... | amino acid and pepto bonds |
| Procedure for testing for carbohydrates | STARCH- fill test tubes with 5 ml of substrate add 5 drops of iodine record color change SUGAR- fill test tubes with 5 ml of substrate add 10 drops of Benedict place in heated water record color change |
| Chemical used in testing for carbohydrates | Iodine (starch) and Benedict (sugar) |
| Color of positive reaction (carbohydrates) | Iodine- blue-black Benedict- orange-red |
| Example of that would test positive for carbohydrates | Iodine- potato Benedict- honey, lettuce, and juice |
| Procedure for testing for lipids | divide a brown paper bag into 10 sections place a sample of each food item in each section place aside and wait for the water to dry positive=grease stain |
| how do you know its a positive reaction ?(lipids) | grease spot |
| Example of that would test positive for lipids | corn oil and butter |
| Procedure for testing for proteins | Add biuret to the substance being tested and look for a color change |
| Chemical used in testing for proteins | Biuret |
| Color of positive reaction (proteins) | purple |
| Example of that would test positive for proteins | yogurt, gelatin, and butter |
| What is "lock and key"? | It describes how there is only on enzyme per substrate much like how there is only one lock for each key. |
| What is the active sight? | The place where the enzyme and the substrate bind. |
| What is activation energy? | the energy needed to start a reaction |
| What does it mean to "denature" an enzyme? | To warp the active site so that the enzyme can no longer bind with its substrate and a reaction cannot take place |
| What does pH and temperature do to an enzyme? | It denatures it. |
| What enzyme is used in the liver lab? | catalase |
| what substrate is used in the liver lab? | Hydrogen Peroxide (H2O2) |
| What is the reactant in the liver lab? | Hyrdrogen Peroxide (H2O2) |
| What is the product in the liver lab? | Water (H2O) ans Oxygen (H2) |
| What is the equation for the liver lab? | H2O2 ---> H2O + H2 enzyme: catalase |
| What is the procedure for the liver lab? | -pour 2ml of water in tube 1 and 2ml of hydrogen peroxide(H2O2) in the remaing 6 tubes -add the liver/potato/sand -measure the reaction by measuring from the bottom of the tube to the top of the bubbles |
| Independent variable in liver lab? | food items |
| Dependent variable in liver lab? | reaction height |
| controlled variable in liver lab? | amount of Hydrogen Peroxide (H2O2) |
