Unit 5: Photosynthesis & Respiration
| Term | Definition |
|---|---|
| energy/ATP | Used to perform an action or do work. During cellular respiration, it is released in the cell by breaking down sugar molecules. |
| photosynthesis | the process that takes place in the chloroplast of plant cells in which energy from the sun is converted into glucose (sugar). Sunlight + water + carbon dioxide ----> glucose + oxygen |
| autotroph | an organism that makes its own food. plants are an example. |
| heterotroph | an organism that gets food from other organisms. Animals are an example. |
| raw materials | the chemical ingredients that go in to a reaction. For photosynthesis, they are sunlight, water, and carbon dioxide. |
| aerobic/anaerobic | requires oxygen / does not require oxygen |
| semi-permeable | some substances can pass through, but others cannot. |
| cellular respiration | process that takes place in mitochondria that breaks down glucose into usable energy (ATP). Glucose + oxygen ---> carbon dioxide + water + ATP (energy) |
| metabolism | all the chemical reactions that take place in an organism to maintain life |
| enzyme | a type of protein that causes or helps a chemical reaction to occur |
