Answer 1

through [metabolic pathways](https://en.wikipedia.org/wiki/Metabolic_pathway), technically speaking i would consider them [non-trivial](https://upload.wikimedia.org/wikipedia/commons/d/da/Gluconeogenese_Schema_2.png), at an ELI5 level “there’s a long series of chemical reactions that end up with stuff your cells can use”
