Which substances are released during cellular respiration? Use complete sentences to explain how the mass of oxygen is conserved during cellular respiration.

The formula for cellular respiration is the opposite of photosynthesis in a way of remembering it. Glucose (C6H12O6) + oxygen to break it down makes 2 waste products. 6H2O (water) and 6CO2 (carbon dioxide) The most important product would be ATP that the cells use for energy, but I am assuming you wanted to know about what is released. Example: When you exercise, you breath in more oxygen which breaks down more glucose which makes more ATP. That’s why you feel tired. And you start to breath out more and release more CO2 as a waste product being released. Hope this helped!

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
