Unit 3: Cell energy- Photosynthesis Flashcards
What is a pigment
Light absorbing molecules
Why are there different pigments in chloroplasts
To absorb as much light as possible
Photosynthetic equation
6CO2+6H2O—-> C6H12O6+O6+6O2
Stroma
Fluid region outside the thylakoid membranes
Thylakoid
Contains Clusters of chlorophyll and other pigments and proteins (enzymes) known as photosystems
Granum
Stacks of thylakoids
What does a light dependent reaction split?
water
What does a light dependent OUTPUT
oxygen, atp, NADPH
what does a light dependent INPUT
oxygen, atp
What does NADPH do
carrier molecules that move high energy electrons. In this case hydrogen molecules
where does the light dependent reaction occur
thylakoid membranes
What does a light dependent reaction require
Light, water, and raw materials
What part of the word photosynthesis is the light dependent reaction
photo
What part of the word photosynthesis is the light independent reaction
synthesis
the Calvin cycle is also known as?
Light independent reaction
What does the light dependent reaction form from carbon dioxide?
Sugar
What does the light dependent reaction form from water?
Hydrogen
Where does the light independent reaction occur
Stroma
what does the light independent reaction INPUT
Carbon DIoxide, ATP
What does the light independent reaction OUTPUT
Sugar
How can water affect photosynthesis
Shortage can slow or stop the process.
How can temperature affect photosynthesis
Temperature not within range may damage enzymes and slows down the process.
How can the intensity of light affect photosynthesis
Increasing light also increases rate of photosynthesis
what does the Calvin cycle give to the light dependent reaction?
NADP, ADP
what does the light dependent reaction give to the light Calvin cycle ?
ATP, NADPH
