| Question | Answer |
| Name the following structure highlighted red in the picture. | Thylakoid |
| Name the following structure highlighted red in the picture. | Grana |
| What is the fluid that is within the chloroplast? | Stroma |
| What is the name of the linkage that links one of the highlight structures to another? | Lamella |
| Oxidation is... | ... the loss of electrons. |
| Reduction is... | ... the gain of electrons. |
| Chlorophyll absorbs light energy... | ... electrons move to a higher energy level. |
| Photoionisation is... | Process by which a chlorophyll molecule becomes positively charged as a result of losing two electrons when absorbing light. |
| When electrons leave the chlorophyll molecule they are taken up by what? | Electron Carriers. |
| What are electrons transfered along? | Electron Transfer Chain. |
| Why are electrons transferred? | Because at each stage of the transfer chain they lose energy (for ATP). |
| Photolysis is... | ... breakdown of water to release protons, electrons, and oxygen. |
| What do the protons gained from the light dependent reaction do? | Together with electrons, produced reduced NADP |
| What is an alternative name for the Light Independent Reaction? | Calvin Cycle |
| In the Light Independent Reaction, what does CO2 react with? | RuBP (Ribulose Bisphosphate) |
| In the Light Independent Reaction, what molecule does CO2 and another molecule, produce? | 2x GP (Glycerate 3-Phosphate) |
| In the Light Independent Reaction, what enzyme catalyses the Carbon Dioxide reaction? | Rubisco (Ribulose Bisphosphate Carboxylase) |
| In the Light Independent Reaction, what is GP reduced to? | Triose Phosphate |
| When GP is being Reduced, what two substances is also required? | Reduced NADP and ATP. |
| What it SOME Triose Phosphate Converted into? | Useful Organic Substances. |
| What is MOST Triose Phosphate Converted into? | Glucose. |
| What is SOME Triose Phosphate USED for? | Regeneration of more RuBP |
| How can the Light Independent Reaction be investigated? | Radioactively Labelled Carbon Dioxide. |
| What Environmental Factors can affect the rate of Photosynthesis. (4 factors.) | > Light Intensity. >Carbon Dioxide Concentration. >Temperature. >Availability of water in the soil. |
| What is the name of the thing that limits the rate of photosynthesis? | Limiting Factor. |
| Where does the Light Dependent Reaction Occur? | Thylakoid Membrane. |
| Where does the Light Independent Reaction Occur? | Stroma |
