Photosynthesis Flashcards
(22 cards)
Photosynthesis takes place in which cell structure/organelle?
Chloroplast
Chloroplasts are in which type of cell?
Plant
What 3 structures make up a Chloroplast? (besides the membrane)
Stroma, thylakoid, and granum
Multiple granum is called
grana
The 2 stages of photosynthesis are
the light reaction and the dark reaction
Another name for the dark reaction is
The Calvin Benson Cycle
Where in the chloroplast does the light reaction take place
thylakoid
Where in the chloroplast does the dark reaction take place?
stroma
Why is one stage known as the light dependent reaction?
the Light Reaction is known as the light dependent reaction because it occurs during the day and needs sunlight to produce ATP and NADPH
What is the green pigment that is “excited” by the sunlight and loses electrons?
Chlorophyll
Where is chlorophyll located?
the thylakoid membrane
Which molecule is split in the Light Reaction?
h2o
3 products of Light Reaction
- ATP
- NADPH
- oxygen
Why is the light reaction important to the dark reaction?
Because it needs the ATP and NADPH that the Light Reaction makes to produce Glucose
Where does the Dark Reaction take place?
stroma
What is the end result of the Dark Reaction?
Glucose
What goes into the dark reaction?
2 ATP, NADPH, 6CO2
What goes into the light reaction?
light energy, 6h2o
What does the light reaction produce?
6O2, 2ATP, NADPH
What can the producer (plant) do with the glucose?
- Store the energy
- Use the energy
- Give away the energy
PHOTOSYNTHESIS FORMULA
6h2o + 6co2 >photosynthesis>6o2 + 1c6h12o6
What is photosynthesis?
The process that organisms use to convert solar energy into chemical energy. (glucose)
