Photosynthesis
Recap photosynthesis
| Question | Answer |
|---|---|
| State the part of the cell where photosynthesis takes place. | Chloroplast |
| Name the two stages of photosynthesis. | Stage 1 = Light reactions Stage 2 = Carbon Fixation |
| In the light reactions is water required or produced. | Required. |
| State the two products when water is broken down in the light reactions. | Hydrogen and Oxygen |
| Explain how ATP is produced in the Light reactions | Light energy is absorbed by chlorophyll and converted into ATP |
| State the energy change in the light reactions. | Light energy to chemical energy |
| Describe the fate of oxygen produced in the light reactions | diffuses out of the leaf. |
| Name the 2 products made in the light reactions which are required for Carbon fixation | Hydrogen & ATP |
| Name the 3 raw materials that are required to be put IN to Carbon fixation | carbon dioxide, hydrogen and ATP |
| Name the ONE product made during carbon fixation. | glucose/sugar |
| State the two molecules glucose can be converted into following Carbon Fixation | starch or cellulose |
| Name the storage carbohydrate | starch |
| Name the structural carbohydrate | cellulose |
| Name the three limiting factors of photosynthesis | Temperature, Light intensity, Carbon dioxide concentration |
| A limiting factor occurs when the graph is a) increasing b) constant | increasing |
