Apologies for the double post, but I have done some research on iron respiration and want to ask if something is possible before I forget.
There is an anaerobic chemical process which uses iron to breakdown glucose, releasing a reduced form of iron, carbon dioxide, and water as a byproduct (according to ChatGPT 
). It is a very ancient form of metabolism and can be an additional form of anaerobic respiration to implement in Thrive.
Knowing this, would it be possible to have an upgrade which requires both iron and glucose to be gathered in order to produce ATP, or is this a bit of a hassle?
