| What term describes an organic molecule that does not dissolve in water? | Hydrophobic |
| What term describes an organic molecule that dissolves in water? | Hydrophilic |
| What characteristic(s) make a molecule more hydrophilic? | The presence of ions or being a polar molecule makes a molecule more hydrophilic |
| Name this functional group: -O-H | Hydroxyl |
| Name this functional group: -C-O-O-H | Carboxyl (see text for geometry) |
| Name this functional group: NH2 | Amino |
| Name this functional group: C=O | Ketone |
| Name this functional group: S-H | Sulfhydryl |
| Name this functional group: C=O-H | aldehyde (see text for geometry) |
| Name this functional group: PO4H2 | Phosphate (see text for geometry) |
| What is the name of the reaction which joins two monomers? | Dehydration Synthesis |
| What is the product of Dehydration Synthesis? | Dimer + Water |
| What is the name of the reaction that breaks apart a dimer? | Hydrolysis |
| What are the five most common monosaccharides? | Glucose, Fructose, Galactose, Ribose, Deoxyribose |
| What are the four major types of organic molecules? | Carbohydrates, Lipids, Proteins and Nucleic Acids |
| What atoms are present in Carbohydrates? | Carbon, Hydrogen and Oxygen (generally in close to a 1:2:1 ratio) |
| What atoms are present in Lipids? | Carbon, Hydrogen and Oxygen (Oxygen is less prevalent in lipids) |
| What atoms are present in Proteins? | Carbon, Hydrogen, Oxygen, Nitrogen and Sulfur |
| What atoms are present in Nucleic Acids? | Carbon, Hydrogen, Oxygen, Nitrogen and Phosphorus |
| What two functional groups must an amino acid contain? | Amino and Carboxyl groups |
| What is the role of glucose, fructose and galactose? | Energy |
| What is the role of ribose and deoxyribose? | Heredity |
| Cellulose is a ______ composed of ______. | Polysaccharide; glucose |
| Name the three common disaccharides, their structure and where found | Sucrose is found in plants and composed of Glucose-Fructose. Lactose is found in milk and composed of Galactose-Glucose. Maltose is found in the intestine from digested starch and is composed of glucose-glucose. |
| What is starch? | Polysaccharide of glucose and performs carbohydrate storage in plants |
| What is glycogen? | Polysaccharide of glucose that performs carbohydrate storage in animals |
| What is cellulose? | Polysaccharide of glucose that provides structural support to plants |
| What is chitin? | Polysaccharide of glucose that serves as some animals' exoskeletons |
| Why does carbon form covalent bonds? | Carbon forms covalent bonds because it does not have a strong tendency to gain or lose electrons |
