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.
Two processes convert ADP into ATP: 1) substrate-level phosphorylation; and 2) chemiosmosis. Substrate-level phosphorylation occurs in the cytoplasm when an enzyme attaches a third phosphate to the ADP (both ADP and the phosphates are the substrates on which the enzyme acts). This is illustrated in Figure 3. Figure 3. Enzymes and the formation of NADH and ATP.
