But I got a bean to coffee machine at home and last night I watched to several lectures by noted biochemist Charlie Lane after he appeared on the Lex Friedman podcast, he talked about the origin of Eukaryote cells 2m years after bacteria (learned that there are two groups who are related but using a different chemistry) and how the Krebbs cycle plays the role in life and death.

Admittedly some of the chemistry was beyond me.
