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. |
