Triple jump triple jump, although this has since been removed from the Olympic program and is rarely performed in competition today. The women's triple jump was introduced into the Atlanta Olympics in 1996. In Irish mythology the geal-ruith (triple jump), was an event contested in the ancient Irish Tailteann Games as early as 1829 BC. The athlete sprints down a runway to a takeoff mark, from which the triple jump is measured. The takeoff mark is commonly a physical piece of wood or similar material embedded in the runway, or a rectangle painted on the runway surface. In modern championships a strip
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
