Buffalo Bob started a radio show with a character named Elmer. The show was so popular his agent and NBC executives suggested that Buffalo Bob should develop a TV show. 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.
The Role of NADH and FADH2. Glucose catabolism ends during the Krebs cycle. This does not mean that all of the energy previously contained in glucose was used in the production of ATP. In fact, only one additional ATP molecule (per molecule of pyruvate) is produced by substrate-level phosphorylation in the Krebs cycle. The balance of extracted energy is tied up in NADH and FADH 2. In the next phase of cellular respiration, the high-energy electrons within NADH and FADH 2 will be passed to a set of membrane-bound enzymes in the mitochondrion, collectively referred to as the electron transport chain. These electrons will provide energy to do work.
