PLAY
Glucose and O2
Products of overall net equation of Photosynthesis?
CO2, H2O and sunlight
Reactants of overall net equation of Photosynthesis?
Glucose
What product does the photosynthesizing organism use?
O2
What is the byproduct of photosynthesis?
Thylakoid membrane and space
Where do the light reactions of photosynthesis occur?
Stroma
Where does the Calvin Cycle of photosynthesis occur?
It captures light energy and coverts it into the stored energy of ATP and NADPH.
What does the light reaction stage of photosynthesis accomplish?
Clusters of proteins surrounded by light-harvesting pigments such as chlorophyll.
What are Photosystem 1 and Photosystem 2 composed of?
H2O
Photosynthesis is a redox reaction. What is Oxidized?
H2O reduced in thylakoid space, Electrons are charged by light reaction.
At Photosystem 2 what happens to H2O?
ATP and NADPH
The light reactions convert light energy into energy stored in:
O2, ATP and NADPH
What are the products of the light reaction stage?
H2O and light energy
What are the reactants used in the light reaction stage?
It takes CO2, ATP and NADPH and creates a glucose molecule.
What does the Calvin Cycle stage of photosynthesis accomplish?
Carbon fixation, reduction and regeneration.
What are the three major phases of the Calvin Cycle?
2 times
How many times must we do the calvin cycle to form a glucose molecule?
Thylakoid space and stroma
During the light reactions, a proton (H+) gradient is developed between what two areas of the chloroplast?
CO2
Photosynthesis is a redox reaction. What is REDUCED?
