PS & Respiration BF
| Question | Answer |
|---|---|
| Photosynthesis | process by which energy is stored in chemical bonds of organic molecules such as carbohydrates |
| Respiration | process by which chemical energy stored in nutrients is released for use in cells |
| Raw material | substances required at the start of a chemical reaction; left of arrow |
| Products | substances produced at the end of a chemical reaction; right of arrow |
| light energy + water + carbon dioxide | raw materials of photosynthesis |
| ATP | high energy molecules generated during cell respiration |
| Oxygen + Glucose | raw materials of cell respiration |
| synthesis | combining simple substances into more complex substances |
| enzymes | specifically shaped proteins that speed up the rate of chemical reactions |
| mitochondrion | organelle that is the site of cellular respiration |
| chloroplast | organelle that is the site of photosynthesis |
| ADP | molecule created when one phosphate is removed from ATP to release stored energy |
| biochemical processes | chemical processes that occur in living organisms |
| chlorophyll | green pigment that absorbs sunlight to drive photosynthesis in plant cells |
| carbon dioxide | gas exhaled by animals; used by plants only |
| oxygen | excess gas released by plants; used by both plants & animals |
| Autotroph | Organism that is able to use a source of energy to produce its food from inorganic raw materials |
| Heterotroph | Organism that cannot produce its own food but obtains energy from the food it eats |
| Pigment | Color substance that absorbs or reflects light |
| Light reactions | Reactions of photosynthesis that require light |
| Dark reactions | Reactions of photosynthesis that do not require light but use energy produced and stored during light reactions to make glucose |
| Photosynthetic Membrane | Chlorophyll-containing membrane in chloroplasts that serves as the side of the light reactions |
| Photosystem | Cluster of pigment molecules within a photosynthetic membrane |
| Electron Transport | Process in which high energy electrons are transferred along a series of electron carrier molecules in a membrane |
