Yes, that’s a promotional image about the contest and not an entry.

It would have probably made a great entry for the contest had it not been made as a promotion…

I suggest some mechanics to develop anaerobic photosynthesis and respiration would be a nice touch for the sake of alternative biology.

Isn’t anaerobic photosynthesis present on Earth already? Even if it’s not, AP can just be put behind non-LAWK. A lot of things can really.

It’d actually be LAWK as early life could perform such processes.

Are there still any anaerobic photosynthesis loyalists left?

I’m not sure what you mean, anaerobic photosynthesis. If you mean photosynthesis that doesn’t make oxygen, some bacteria do that. Some bacteria also use light to turn food into ATP instead of oxygen like us normal, aerobic, life forms. This doesn’t involve CO2 I think.

Yeah I was supposed to mean that.

Okk, thanks for clarifying! I believe that some bacteria use reduction reaction to do that sort of photosynthesis, which implies to me they’d be reliant on hydrogen or other chemicals, but I haven’t done very (read: any) in depth research (I’m in assembly class rn, it’s too interesting to do organic chemistry research).

We’ll see if developers consider this feature important enough to add…
Spoiler: it’s nowhere near our roadmap, so basically only if someone really wants such a feature, they need to design and then program it themselves, would it be added.

The power of open source!

Honestly, sounds like a good mod or fork feature.

would it be seperate from thykaloids (or whatever were they called) or would it be an upgrade or the base form of them?

It would be interesting to have a full Anoxic World scenario where life never evolved to utilize oxygen.

That would also require all the produced oxygen to be removed from the environment, or else the growing concentrations would end up becoming toxic.

Light is an energy source. You don’t need light to break down glucose. You don’t need anything.
You can use oxygen to burn it
1/6 C6H12O6 + O2 => H2O + CO2 + atp
You can use sulfuric acid to burn it. Which is not a gas so it can only happen in water
1/6 C6H12O6 + 1/2 H2SO4 => H2O + CO2 + 1/2 H2S + atp
Or you can use iron oxide to burn it. Which can only happen at the bottom of lakes because iron oxide is a solid. It must’ve been common during the great oxygenation because all the iron in the ocean was oxidising and sinking.
1/6 C6H12O6 + Fe(III)2O3 => CO2 + Fe(II)(OH)2 + atp
Or you may use nothing! to break it down. Which is what we do with fermentation
If you generate methane, you are called a methanogen. And the process is called methanogenesis.
1/3 C6H12O6 => CO2 + CH4 + atp
If you generate acetate, this is called acetogenesis
C6H12O6 => 3 C2H4O2 + atp
some hydrogen can get released as well
Fermentation that happens in our bodies starts the same was as acetogenesis. Its like an incomplete acetogenesis. Also luca was an acetogen.
In terms of the energy generated per glucose, it is oxygen>iron oxide>sulfate>methanogen>acetogen>fermentation
Light is used for making glucose in photosynthesis. It is never used for breaking down glucose.
There is also photoheterotrophy that the oriental hornet does
adp + p + light => atp
It would still need to eat glucose. Because even though it doesn’t need it for energy (so, possibly no starvation), it still needs to get reduced carbon from the environment in order to grow and increase its biomass.
There is also hydrogenotrophy which is where you “burn” hydrogen using carbon dioxide. It is the only instance where burning something creates glucose. (if we aren’t talking about titan-like or hycean planets)
2 H2 + CO2 => 1/6 C6H12O6 + H2O
Luca was a hydrogenotroph. And an acetogen at the same time. The former is its autotrophy type, how it makes glucose, and the latter was the way it broke down glucose.
There are lots of anaerobic metabolism types. I should make a chart about it.

Acetogenic life forms are my favorite, all the best food is left for them to eat for a while before I eat it.
so much fun stuff in that mess.

I wonder just how much stuff will be there in the non-LAWK category by the microbe stage full release…
