On 17 December, 1947, Buffalo Bob launched the 'Puppet Playhouse'. Within a week the show's name was changed to 'The Howdy Doody Show'.
However, usually most of the ATP is generated by oxidative phosphorylation in aerobic or anaerobic respiration. Substrate-level phosphorylation serves as fast source of ATP independent of external electron acceptors and respiration.
Glycolysis and oxidative phosphorylation is two, and then there is also the citric acid cyle (also caled the Kreb's cycle). Substrate-level phopshorylation happens in both glycolysis and the Kreb's cycle. The only difference is that the Kreb cycle is also in the mitochondria and glycolysis is not (it's in the cytoplasm).
