Photosynthesis Flashcards
What does triphosphate mean?
Three phosphates
Where is chemical energy stored?
Chemical bonds
What does a high frequency on the light spectrum mean?
High energy
How many cycles does it take to produce one molecule of glucose in the Calvin cycle?
6
What is a Granum?
Multiple stacks of thylakoids
What is a Grana?
One stack of thylakoids
The Calvin cycle constructs G3P using what?
Carbon from CO2, electrons from H+ and NADPH & energy from ATP
What is the flow of electrons during photosynthesis?
water→NADPH→Calvin cycle
Why is NADPH important in photosynthesis?
It carries hydrogen atoms and high-energy electrons for producing organic molecules
What do the light-independent reactions produce?
ATP & NADPH
Plants use energy from the sun to convert carbon dioxide and water into what?
Glucose
During this process, carbon from carbon dioxide (CO2) is incorporated into organic molecules.
Calvin Cycle
What is the role of carbon dioxide in photosynthesis?
Carbon dioxide is fixed in the Calvin cycle, which eventually results in the production of glucose
What does the light-dependent reaction produce?
ATP, NADPH, Oxygen
Where does the Calvin cycle take place?
Stroma
Where does light-dependent reaction occur?
Thylakoid membrane
The rate of photosynthesis depends on the?
Intensity of light and temperature
What is one component in photosynthesis that is not recycled and must be constantly available?
Sunlight
What is the chemical equation for photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
How do plants store excess glucose for later use?
In the form of Starch
What is a heterotroph?
An organism that consumes to get energy
What is an autotroph?
An organism that makes its own food
Which wavelengths of light are best absorbed by chlorophyll a & b?
blue and red
Which wavelengths of light are reflected?
Green
What is a pigment?
an objects color
What happens to water during the light-dependent reaction?
water is split
