(15 cards)
Which organelle does photosynthesis take place in?
The chloroplast
Where are chloroplasts found?
In photosynthetic plant cells
How many membranes are there in the chloroplasts?
2
What are thylakoids?
The envelope consisting of many flattened sacs
What are stacks of thylakoids called?
Grana/ granum
Which part of photosynthesis takes place in the thylakoids?
Light dependent reaction
What is the membrane system surrounded by?
The stroma
Which part of photosynthesis takes part in the stroma?
Light independent reaction
What is the overall equation for photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
What are the conditions that would affect photosynthesis?
Carbon dioxide, water, light, chlorophyll, a suitable temperature for enzymes
What does photosynthesis involve?
Formation of organic compounds by the reduction of carbon dioxide
Where is the hydrogen obtained to do this?
The light induced breakdown of water (photolysis)
What is ATP required for?
The synthesis of organic molecules
How is ATP produced in photosynthesis?
By the conversion of light energy by photophosphorylation
What are the two stages of photosynthesis?
Light dependent reaction, light independent reaction
