Long jump at the Olympics gold medals in its brief history. From 1900 to 1912 a variation of the event was contested at the Olympics where athletes had to long jump from a standing position. This was one of three standing jumps to have featured on the Olympic programme, alongside the standing high jump (present for the same period) and the standing triple jump (1900 and 1904 only). The standing jump competitions were dominated by Ray Ewry, who won the Olympic standing long jump titles in 1900, 1904 and 1908. His clearance of at the 1904 Olympics remained as the Olympic record for the event
Committed step Committed step In enzymology, the committed step (also known as the "first" committed step) is an effectively irreversible enzymatic reaction that occurs at a branch point during the biosynthesis of some molecules. As the name implies, after this step, the molecules are "committed" to the pathway and will ultimately end up in the pathway's final product. The first committed step should not be confused with the rate-determining step, which is the slowest step in a reaction or pathway. However, it is sometimes the case that the first committed step is in fact the rate-determining step as well. Metabolic pathways require
