AI Thread Summary
The discussion centers around the Calvin cycle, specifically the role of ribulose bisphosphate and its conversion into a transient 6-carbon sugar before forming phosphoglyceric acid. There is curiosity about synthesizing rubisco to clarify its structure and mechanism, with an acknowledgment that this may be more complex than it appears. While rubisco has been sequenced, the difficulty in identifying the 6-carbon intermediate remains unclear. Participants express frustration over the lack of accessible information on this specific aspect of the Calvin cycle. The conversation highlights the challenges in researching biochemical processes and the need for more detailed studies on intermediates.

I have been learning about the calvin cycle, and have been told that people think that ribulose bisphosphate is first converted into a 6 carbon sugar as a very short life intermediate, and then is converted to phosphoglyceric acid.
Why can't you just synthesise rubisco, work out its structure and mechanism of action etc. and then find if that is true. I'm sure its a lot harder than I'm thinking of it being, but how much?

have you tried google?
 
I hadn't. Now I have though, I know that they have sequenced it, but still don't know about the intermediate, surely it would be easy to find... why is it so hard?

I've tried it. Couldn't see anything about the 6 carbon intermediate though.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
