The next phase of aerobic respiration is the Citric Acid Cycle, also known as the Kreb's Cycle, named for the biochemist who discovered it. To prepare for this stage, the pyruvate molecules from glycolysis are converted to a 2-carbon compound called Acetyl CoA.
Commercial pilots working in nonscheduled air transportation earned $78,010 on average in 2011, the bureau says. Those employed by technical schools and trade schools averaged $66,070, and workers providing support activities for air transportation earned $71,440.
This is far more than most commercial pilots, who reported an average income of $76,050 in the same year. For example, pilots employed by the agricultural industry made an average of $61,010 in 2011, while life-flight pilots averaged $68,090 per year.
