Ch 15 - Energy and Biomolecules
| Question | Answer |
|---|---|
| The ability to do work | Energy |
| The energy an object has due to its motion | Kinetic Energy |
| Energy that is stored as a result of position or shape | Potential Energy |
| Potential energy that depends upon an objects height above a reference point | Gravitational Potential Energy (GPE) |
| Potential energy of an object that is stretched or compressed | Elastic Potential Energy |
| Energy that is associated with motion and position of everyday objects | Mechanical Energy |
| The total potential and kinetic energy of all the particles in an object | Thermal Energy |
| The energy stored in chemical bonds | Chemical Energy |
| The energy associated with electric charges | Electrical Energy |
| A form of energy consisting of changing electric and magnetic fields | Electromagnetic Energy |
| The energy stored in atomic nuclei | Nuclear Energy |
| Changing one form of energy into another. | Energy Conversion |
| Energy can not be created nor destroyed. | Law of Conservation of Energy |
| A source of energy that is limited and can not be replaced. | Nonrenewable Energy Resources |
| Hydrocarbons formed from the remains of plants and animals (over millions of years). | Fossil Fuels |
| Energy sources that can be replaced in a short period of time. | Renewable Energy Resources |
| Energy obtained from moving/flowing water. | Hydroelectric Energy |
| Sunlight that is converted into useable energy. | Solar Energy |
| Thermal (heat) energy from beneath the Earth's surface. | Geothermal Energy |
| The chemical energy stored in living things. | Biomass Energy |
| The energy needed to heat up one gram of water by 1 degree. | Calorie |
| Kinetic Energy depends on this and the mass of an object. | Velocity |
| Changes KE into Thermal energy. | Friction |
| Made up of sugars, from one to thousands. | Carbohydrates |
| Made up of combinations of the 20 amino acids. | Proteins |
| Made up of glycerol (an alcohol) and three fatty acid carbon chains. | Lipids |
| Type of lipid that is solid at room temperature and found in animals. | Fat |
| Type of lipid that is liquid at room temperature and found mostly in plants. | Oil |
| Made up of many, many combinations of nucleotides. | Nucleic Acids (DNA, RNA) |
| Used by the body for short term energy. | Carbohydrates |
| Used as the worker molecules that do most of the work throughout your body. | Proteins |
| Long-term energy storage in your body. | Lipids/Fats |
| Stores your genetic information from your parents. | DNA |
| Contains 9 calories per gram. | Lipids |
