To the mesophyll
High concentration of chloroplasts
That's where all the stuff goes down
So this story's gonna be action packed

Through xylem cells in the veins
Goes an h2o up from the roots
A CO2 into a stomate
Photons absorbed by a leaf's face (face-ace)

Chlorphyll a, b, carotenoids
Are all so energized
Pass on ke of the light
To the reaction center. P

P680's excited, electrons loosened
Passed onto the primary electron acceptor (plastiquinone)
H2o replenishes its electrons (photolysis)
H+ into the lumen
O2's excreted! :D

Plastiquinone to cytochrome b6f
Then plastocynine to photosystem I
They carry electrons and are proton pumps
It's an electron transport chain

It's exergonic
The moving of the electrons
Which powers the pumping of protons
From low to high concentrations

Photosystem I
P700's re-excited
There's another ETC
It's smaller this time
Final Acceptor: NADP(+)
Reduced to NADP

Now here's chemiosmosis
H+ protons fall back from
The lumen to the stroma

This happens cause of the concentration gradient
Since the stroma's relatively negative
H+ falls back through ATP synthase
Go to the stroma!

What just happened is known as the light reactions
Now into the stroma for the dark reactions
Also known as the famous "Calvin Cycle"
CO2's invested
To make some glucose!

Take three CO2
Add some RuBP
Carbon fixation
Make 6 PGA

The 6 ATP and 6 NADPH
Are invested to reduce the 6PGA
Into the 6 G3P's—1 is released
To make some glucose
The 5 reform RuBP

The Calvin Cycle turns thrice for one G3P
2 G3P make one glucose (gluconeogenisis)
Glucose is used for storage, biosynthesis
Cell resp for ATP
