Photosynthesis: Calvin Cycle
You probably know that plants take in carbon dioxide and give out oxygen, but as we saw in the last article, that isn’t a neat exchange, turning O2 into CO2. Rather, oxygen is created as a byproduct of splitting water, and CO2 is consumed by being turned into sugar. This happens in the Calvin Cycle.
In the Calvin Cycle, carbon dioxide, NADPH, and ATP are put in, and a sugar called G3P comes out. There are three steps to create this sugar: carbon fixation, reduction, and regeneration. Note that none of these steps needs direct light!
The first step is carbon fixation. CO2 is taken in from the atmosphere around the plant, added to a 5-carbon sugar called RuBP (ribulose bisphosphate), and thus turned into 3-phosphoglycerate, an organic molecule. This process is catalysed by an enzyme called Rubisco—basically, it recognises CO2 and pairs it with the “CO2 acceptor”, RuBP. For every “turn” of the Calvin Cycle, three CO2 molecules are fixed into two 3-phosphoglycerate molecules.
In the second step, reduction, the cycle takes in 6 NADPH and 6 ATP (from the light reactions) to convert these molecules into glyceraldehyde 3-phosphate (G3P). The “reducing power” of NADPH is used to add electrons to the molecules, and the ATP gives them phosphate groups.
Then in the last stage, regeneration, 3 more ATP molecules are used to turn five molecules of G3P back into RuBP, the CO2 acceptor, so it can be used again at the start of the cycle. What’s leftover—a single G3P—is the output of the cycle. It’s the overall goal of photosynthesis: a sugar molecule that can then be used in cellular respiration to create energy for living cells to use.

So, a roundup of the cycle:
We put in 9 ATP, 6 NADPH, and 3 CO2.
We get out 9 ADP, 6 NADP+, and 1 G3P (plus 3 RuBP molecules).
The ADP and NADP+ are then recycled back to the light reactions, and photosynthesis begins over again.

earthstory:

This weekend marks the 45th anniversary of the first humans walking on the Moon, the Apollo 11 mission. Here’s one of the images from that mission in gif form; the famous Earthrise, as seen from the Command Module spacecraft that remained in Lunar Orbit while 2 astronauts descended to the surface.

Hey you, hey you, #Devil’s little sister
Listening to your #Twisted #Transistor
Hold it between your #legs
Turn it up, turn it up
Low end is coming through
Can’t get enough

A lonely life, where no one understands you
But don’t give up, because the music do
Music do

Because the music do
And then it’s reaching
Inside you forever preaching
Fuck you too
Your scream’s a whisper
Hang on you
Twisted Transistor

Hey you, hey you, finally you get it
The world ain’t fair, eat you if you let it
And as your tears fall on
Your breast, your dress
#Vibrations coming through
You’re in a mess

A lonely life, where no one understands you
But don’t give up, because the music do
Music do

Because the music do
And then it’s reaching
Inside you forever preaching
Fuck you too
Your scream’s a whisper
Hang on you
Twisted Transistor
Music do, #Music do

Hey you, hey you, this won’t hurt a bit
This won’t hurt a bit, this won’t hurt
Says who? Says who?
#Anesthetize this bitch
Anesthetize this #bitch, anesthetize!
Just let me be
Between you and me don’t fit

Because the music do
And then it’s reaching
Inside you forever preaching
Fuck you too
Your scream’s a whisper
Hang on you
