That’s cellular respiration! The mitochondria, THE POWERHOUSE OF ALL CELLS EVERYWHERE, does that one! It’s the one that keeps life living. 3 ADP -> 2 ATP iirc.

Krebs, Couldn’t live without it.

Easy:

1. Kreb eat
2. Krab make baby krabs
3. Old crab die
4. Baby crabs grow
   And so the crab cycle repeats

To be fair, the way the Krebs cycle is taught is usually pretty grim (speaking as a biochemistry major)
