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
