cellular respiration
| Question | Answer |
|---|---|
| ATP | The form of chemical energy cells use to do their work. |
| Autotroph | An organism that can make its own food. |
| Bromothymol Blue (BTB) | An indicator in determining pH; it can turn from blue, to green, to yellow! |
| Carbon dioxide | A product of cellular respiration. It is needed for photosynthesis. It is a gas. |
| Cellular respiration | The process by which organisms use oxygen to break down food molecules to get chemical energy for cells to do their work. |
| Chemical energy | The energy that is stored in the bonds of atoms and molecules. |
| Chemical equation | A process that shows how substances are combined together to create new substances. |
| Chloroplast | The organelle that does photosynthesis; it makes food for plants, some bacteria, and some protists. |
| Consumer | An organism that has to eat other organisms for food. A synonym is heterotroph. |
| Eukaryote | An organism that has a cell or cells with a nucleus. |
| Food chain | The order in which organisms depend on each other for food. |
| Glucose | The sugar that is the main source of energy for cells; it is the sugar produced by photosynthesis. |
| Heart | The organ that pumps blood throughout the body. |
| Heterotroph | An organism that has to eat other organisms for food. |
| Lungs | The organ that puts oxygen into the blood and takes carbon dioxide out of the blood. |
| Mitochondrion | The organelle that does cellular respiration; it provides the cell with energy. |
| Organ | A structure made of different tissues that work together to perform a specific function. |
| Organelle | A part of a cell that does a specific job. |
| Organism | A living thing made of one or more cells. |
| Oxygen | A product of photosynthesis. It is needed for cellular respiration. It is a gas. |
| Photosynthesis | The process by which a plant makes its own food. |
| Producer | An organism that can make its own food. A synonym is autotroph. |
| Product | A substance that gets created in a chemical equation. |
| Prokaryote | An organism that does not have a cell with a nucleus. |
| Rate | A ratio that compares two quantities with different units of measure, like heart beats per minute. |
| Reactant | A substance that gets combined with another substance in a chemical equation. |
| Respiration | Breathing in and breathing out; the exchange of oxygen and carbon dioxide in the lungs. |
| Respiratory System | The many organs that work together that allow you to breathe. |
| Sugar | A product of photosynthesis. It is needed for cellular respiration. It is a solid. |
