Photosynthesis
| Question | Answer |
|---|---|
| What types of organisms do photosynthesis? | plants, algae, some types of bacteria |
| what is the purpose of photosynthesis? | to make food (glucose) for plants, which is then used to make ATP energy |
| What is the formula for photosynthesis? | 6CO2 + 6H2O ----> C6H12O6 + 6O2 LIGHT |
| What are the reactants of photosynthesis? | carbon dioxide and water |
| what are the products of photosynthesis? | glucose and oxygen |
| where does photosynthesis occur? | in the chloroplast of plants: light reactions in the thylakoids; Calvin cycle in the stroma |
| what are the 2 reactions of photosynthesis? | light-dependent reaction and light independent reaction (aka Dark reaction or Calvin Cycle) |
| What happens during the light-dependent reaction of photosynthesis? | the plant uses light, water, adp and nadp+ electron carrier to make ATP and NADPH which are needed to run the Calvin Cycle. Oxygen is produced as a waste product |
| What happens during the light-independent reaction of photosynthesis? | ATP, NADPH, and carbon dioxide are used to make glucose. ADP and NADP+ are also formed, which are needed for the light reaction |
| what is considered a waste product of photosynthesis? | oxygen--it is release from the plant since it is not needed, which benefits animals... |
| where does the carbon to make glucose in the calvin cycle come from? | animals breathe out CO2 during cellular respiration, which is used by plants during the calvin cycle. |
