| A | B |
| Addiction | A physical dependence on a substance or feeling (it doesn't always have to be illegal). |
| ATP | The energy created as a result of cellular respiration (we make this energy by breaking down sugar) |
| Beta Oxidation | The process by which animals use oxygen to make energy |
| Calories | How energy from food is measured |
| Carbohydrates | Are nutrients that can be broken down to release energy QUICKLY. Ex: grains, breads, potatoes, corn, fruit, sugars |
| Cell | The basic unit of structure in all living things. Some organisms like bacteria have only one, while other organisms like humans, have millions |
| Cellular Respiration | The process by which cells break down sugar to release stored energy. This equation is the opposite of photosynthesis: Glucose + Oxygen --> Water + Carbon Dioxide + ATP energy |
| Circulatory System | The system that includes the heart and blood. The circulatory system delivers nutrients and gases to cells throughout the body |
| Diet | The amount and types of foods one consumes. |
| Digestive System | Includes the mouth and stomach--food is taken in and broken down into smaller molecules that can be used by cells |
| Drug | A substance that causes a change in a persons body or behavior |
| Energy Balance | When energy in = energy out. When energy balance does NOT occur people may gain or lose weight |
| Lipids | The word for "Fat". These can be oils (vegetable fat) or solids (animal fats). Fat is a form of stored energy |
| Meiosis | A process where cells divide for sexual reproduction. The parent splits into 4 different daughter cells each with half the number of original chromosomes |
| Metabolism | The set of chemical reactions involved in storing food and converting food molecules into energy |
| Mitosis | Asexual reproduction of cells in which one cell splits into two identical daughter cells |
| Nucleic Acids | DNA or RNA that carry the code for the synthesis of the organism's proteins. |
| Nutrient | The compounds that provide building materials for living things. There are 3: proteins, compounds, and lipids |
| Photosynthesis | The process in which the cells of plants use light energy from the sun to make chemical energy in the form of food. Solar Energy + Water + Carbon Dioxide --> Glucose + Oxygen |
| Proteins | Nutrients used for growth and repair, also found in bones and connective tissue and come from lean meat. |
| Respiratory System | The system that includes the lungs. Oxygen from the air is passed to the circulatory system and used to break down food in the digestive process |
| Thermal Energy | Energy released as heat |
| Toxic | Harmful to the body. |
