Photosynthesis 2.9 Flashcards
Understanding of photosynthesis
- What is the production of photosynthesis?
- Production of carbon compounds in cells using light energy
Understanding of photosynthesis
- What is produced in photosynthesis/ from what?
- Oxygen is produced in photosynthesis from the photolysis of water
Understanding of photosynthesis
- Why is energy needed?
- Energy is needed to produce carbohydrates/ other carbon compounds from CO2
Purpose
- What do plants have the ability to do
- Ability of plants to capture the energy of light and turn it into the chemical energy - organic food molecules
- How plants make their food
Light dependent reactions
- What does chlorophyll do/ where is it
- On the Thylakoids in chloroplast
- Absorbs light
Light dependent reaction
- Converts …… into chemical energy
- What does it split?
- Chemical energy (ATP)
- Water into H2 and O2 (photolysis)
Light dependent reaction
What happens to H2 in light dependent reaction (carried)/ by what molecule?
- H2 is carried to light dependent reaction by carrier molecule NADP
Light dependent reaction
- What is released from cell
- O2 is released from cell
Light independent reaction
- What does it use ATP to do/ were?
- Combine CO2 and H2
- Stroma
Light independent reaction
- What does this reaction use
- Enzyme = Rubisco
Light independent reaction
- What does this reaction synthesises?
- Glucose (C6-H12-06)
- What is photolysis?
- What is it’s purpose?
- Splitting water into H2 and O2
- Purpose variable of the light dependent reaction
What is the role of ATP in photosynthesis?
- Converts light energy into chemical energy (ATP) - light dependent reaction
What is the role of NADP in photosynthesis?
- Carrier molecule NADP - carries H2 to the light independent reaction
