It has now been eight and a half years since coalition forces led by the U.S. launched air strikes against the Taliban, starting the war in Afghanistan. That, according to Diane Sawyer in ABC Online, gives the conflict a fresh and dubious distinction â it has surpassed the length of the Vietnam War to become the longest war in U.S. history.
The equation that describes aerobic cellular respiration is Glucose  plus Oxygen which equals Carbon Dioxide plus water plus energy.  Respiration is the gas exchange and cel â¦ lular respiration produces  ATP.
1. The presence of oxygen in the cells determines which type of cellular respiration will work, and in this case, aerobic respiration uses oxygen to produce energy in the form of ATP, with water and carbon dioxide as by-products. If oxygen is absent, the cells still produce energy, this time using anaerobic respiration.
