can either suicide via Autophagy or send cytochrome C signal
My limited understanding is that can is the key word. There are apparently factors that can lead to the cell switching from OxFox to the primitive method of ATP generation which may actually be the original default state of operation for the cell prior to mitochondria being introduced. This may be an early state that existed prior to there being much O2 in the atmosphere when lifeforms were much more primitive. Again, this is not my area of expertise and I am not sure that scientists fully understand this yet either.
- SemanticStrengh 5y agoWait what? What is the name of the primitive energy generation you refer to? I am only aware of https://en.m.wikipedia.org/wiki/Anaerobic_glycolysis https://en.m.wikipedia.org/wiki/Anaerobic_glycolysis And it is too limited: providing energy for a period ranging from 10 seconds to 2 minutes.
- photochemsyn 5y agoProbably is referencing the reverse Krebs cycle, which can be used to build up organic molecules from free H2 and CO2 by anaerobic bacteria. > "The ‘reverse’ Krebs cycle was first proposed in 1966. It does exactly the opposite; it uses energy to react the gases hydrogen and carbon dioxide to make Krebs-cycle intermediates, turning simple gases into the molecules of life. The bacteria that live this way are a billion years older than the first photosynthetic cyanobacteria and thrive in environments where life might have started, such as hydrothermal vents." https://www.ukri.org/blog/understanding-the-origins-of-life-helps-address-major-challenges/ https://www.ukri.org/blog/understanding-the-origins-of-life-...
- SemanticStrengh 5y agoInteresting. 1) mammal cells are unable to do reverse Krebs? 2) do reverse Krebs produce oxygen?
