| Question | Answer |
|---|---|
| What are the three types of photosynthesizers? | plants, algae and bacteria |
| Name two wavelengths (colors) of light that plants absorb the best. | Blue and red |
| The major organ of photosynthesis in plants. | chloroplast |
| Where is the chloroplast does the light-dependent reaction part of photosynthesis take place? | thlakoid membrane |
| Where is the chloroplast does the light-independent reaction part of photosynthesis take place? | stroma |
| Primary pigment of photosynthesis | chlorophyll |
| accessory pigments of photosynthesis | carotenoid (orange) & xanthophyll (yellow) |
| This enzyme carries electrons from the light-dependent reactions to the light-independent reactions. | NADPH |
| Two components of the light dependent reactions. | Photosystem I & photosystem II |
| Where do the electrons come from in light dependent reactions? | Water that is stripped. |
| This alternate cycle works for cactus, pineapple and orchids. | CAM |
| A process in which the enzyme rubsico undercuts carbon fixation in photosynthesis by binding with oxygen instead of carbon dioxide. | photorespiration |
| Plants keep their stomata closed during the day and open at night in what form of photrespiration. | CAM |
| When rubisco oxygen instead of carbon dioxide ad no growth occurs. | Photosynthesis |
| site of photosyntheesis | chloroplast |
| Releases the energy stored in the chemical bods of food. | cell respiration |
| The currency of cellular energy. | ATP |
| The synthesis reaction of photosynthesis. | light-independent reaction |
| Uses the sun energy to build carbohydrates. | photosynthesis |
| Why is the C4 pathway called c4? | Because it initially fixes CO2 into a 4-carbon molecule. |
| Its products are used on the Calvin cycle. | light-dependent reaction |
| What is the initial electron donor in photosynthesis? | H2O |
| What are the products of photosynthesis? | Oxygen and plant material |
| What is the key enzyme in the light-independent reactions of photosynthesis? | rubisco |
| Half of a glucose molecule. | G3P |
