Can you provide a source for point D2? Admittedly, I don’t understand chemistry at all, but that seems strange to me, and I’d like to read more

If I can find the paper I'll link it later. I stumbled across it by accident while researching something else. But I read about it a week or so before this video came out briefly mentioning it: https://youtu.be/myxVsYI4WZk?t=531

This is not the article I read, but doing a quick "carbon 13 plant absorbing" search pulled this up as a top place: http://www.plantphysiol.org/content/plantphysiol/36/2/133.fu... Under controlled conditions, plants favor c12 to c13. But it's an old study(61) and there's been more recent work. Plus on different photosynthesis types. This paper doesn't seem to go through the different types. But yea, should give you a start.

I swear I'm looking for a paper done by Michigan State. But I can't find it. I'll update if I find it.

Hey, I appreciate it, just having a few search terms can go a long way. Like I said, my knowledge in chemistry is practically non-existent, and I basically forgot isotopes exist, so this'll get me going. Thanks!

I agree with you on that. In all my years of biology, I've never heard of a distinction of CO2 source mentioned even once.
