So in this question, we are addressing plants that do carbon fixation at night.
00:22
Okay.
00:24
If they're doing carbon fixation at night, that means they're storing their co2.
00:38
Okay, because you really can only do calvin cycle during the day.
00:52
Calvin cycle needs light reactions.
00:59
Now remember, a calvin cycle is called the dark cycle.
01:02
The calvin cycle, it doesn't need light in of itself, but it needs the light reaction products.
01:14
Remember, atp and nadph for energy.
01:28
So you need to talk about plant that has an adaptation for storing co2.
01:33
Okay, now some plants can take phospholeno pyruvate and join co2 to form oxaloacetic acid or oxaloacetate.
02:10
And that oxalocetic acid can now form malate or malic acid.
02:19
It, and then it's stored...
