Using sunlight to make food (sugar)
6CO2 + 6H2O ­­> C6H12O6 + 6O2
Opposite
Organism that makes it's own food
An autotroph
Uses light to make its own food
Pigment that captures photons of light
Layer of tissue in a leaf where photosynthesis occurs
Pores on the underside of leaves where gas exchange occurs
Where the dark reaction occurs in a chloroplast
Discs in a chloroplast where the light reaction occurs
Stacks of thylakoids
Using light to make ATP and NADPH
Fixing CO2 to make sugar using ATP and NADPH
CO2 bonding to RUBP to make a 6C molecule that splits
Particle of light
Group of pigments that capture light in the thylakoid
How ATP is made in the light reaction
1
Inner membrane
Thylakoid
Stroma
Grana
CO2 through the stomata, H2O through the roots
water splitting
CO2
H2O
To make ATP and NADPH for the dark reaction
Light is required to excite the electrons
To make sugar (G3P)
ATP and NADPH are used in the dark reaction
ATP and NADPH
Pigment molecules
Water splitting
The sun (light)
Another pigment molecule
NADP+
2
Photophosphorylation
They are used in the dark reaction which takes place in the stroma
Carbon fixation ­­ CO2 bonds with RuBP = 6C molecule that splits
Reduction ­­ PGA gets reduced by NADPH with the help of ATP to make G3P
Regeneration ­­ 5 G3P reform into 3 RuBP which uses 3 ATP to do so
6 (3 for each G3P)
Rubisco is the enzyme that bonds CO2 to RuBP.
If this didn't work, then no ATP's or NADPH's would be used. Therefore, the plant would eventually run out of raw materials (ADP, P, and NADP+). It would eventually stop.
