Slightly unrelated to the topic at hand but did this evolve in species after they started becoming more physically active? I wouldn't think that bacteria would have any use for this pathway within this specific context (generating lactic acid to meet demand for energy due to exercise). Also how important is the production of lactic acid; does the acid itself have benefits or is it simply a byproduct/tradeoff?

I think this is implying that ADP came first and then ATP evolved from ADP but this leads me to think about how ADP came into existence. I dont think its a case similar to the phospholipid bilayer where it just happens if theres enough of the needed molecules floating around and without ATP which is what releases energy after turning into ADP, I don't understand its function or importance in organisms before

Would this be referring, then, to explicit meaning or implicit meaning -- or neither?

This is where you can type your notes.

I am not sure I understand perfectly what was said here, however, if what I believe it is being said is right I think this is a very interesting sentence. Son of God is a statement made by us, which is sufficient by itself but also by greek philosophers? As a reinforcement of this statement?
