Bio Unit 2
| Term | Definition |
|---|---|
| Adhesion | Water molecules stick to other objects |
| Cohesion | Water molecules stick to each other |
| Surface Tension | Water molecules form a film on the surface of the water |
| Capillary Action | Water “climbs” up against gravity |
| High specific heat | Water resists temperature changes |
| Water has different densities | Changes with temperature or if there's substances dissolved in it. |
| Water is the universal solvent | Water dissolves most anything! |
| High heat of vaporization | The amount of heat necessary to cause a phase transition between a liquid and a gas; Large amount of heat is needed to vaporize liquid |
| pH | Measure of acidity/alkalinity |
| Water moves up the water vessel (xylem) of a plant against gravity | Capillary Action |
| A water strider can walk on water | Surface Tension |
| Ice insulated pond water in winter, helping organisms stay warmer | Expands when frozen |
| Water dissolved nutrients and minerals in our blood | Universal Solvent |
| Climate near the coast is more temperate than the climate in the desert | High specific heat |
| Sweat removes the high energy water molecules from the body, cooling the skin | High heat of vapirozation |
| Monomer of Proteins | Amino Acids |
| Monomer of Nucleic Acid | Nucleotides |
| Monomer of Carbohydrates | Monosaccharides |
| Elements in Proteins | C,H,O,N and sometimes sulfur |
| Elements in Nucleic Acids | C,H,O,N,P |
| Elements in Carbohydrates | C,H,O in a 1:2:1 ratio |
| Elements in Lipids | C,H,O(P, phospholipid) NOT in a 1:2:1 ratio |
| Dehydration Synthesis | 2 molecules come together and form a larger molecule by removing water. It's important for building complex biological molecules like carbs, proteins, and lipids. |
| Hydrolosis | The compound breaks down into smaller molecules by adding water. The opposite of dehydration synthesis |
| Starch | Energy storage in plants |
| Glycogen | Energy storage in animals |
| Cellulose | Makes up cell walls (plants) |
| Chitin | Makes up exoskeleton |
| Saturated Fats | Solid fats Solid at room temperature Fatty acids do not have double bonds between the carbon and hydrogen in the fatty acid chain |
| Unsaturated Fats | Liquid fats Liquid at room temperature Fatty acids have double bonds between the carbon and hydrogen in the fatty acid chain |
| What type of macromolecule is an enzyme | Proteins |
| Can enzymes be reused | Yes |
| Enzyme | Proteins that speed up reactions |
| Active Site | Enzyme’s catalytic site; substrate fits into active site |
| Substrate | Reactant that binds to enzyme |
| Reactant | Substance that undergoes a change during a reaction |
| Product | End result of a chemical reaction |
| Denaturation | When enzyme loses its shape and will no longer work |
