Set 15 – Lab 8: Aerobic Cellular Respiration Notice the two sensors that measure the concentration of gases in the air inside the tank in each video: The O2 gas sensor measures the concentration of oxygen gas in the air in the tank in percent. The CO2 gas sensor measures the concentration of carbon dioxide gas in the air in the tank in parts per million (ppm). The normal concentration of gases in air are: CO2: 400 ppm outdoors, 500-800 ppm indoors O2: about 20% outdoors, 19.5-20% indoors Question: Which is greater in the concentration of normal air; the concentration of oxygen gas or carbon dioxide gas?
