What is cellular respiration?

  • Cellular respiration is a process carried out by the cells of an organism to break down glucose into usable energy (ATP)
  • Glucose and oxygen are needed for this process
  • Carbon dioxide and water are by-products of this reaction

How is cellular respiration related to what you measured in the cricket lab?

  • In the cricket lab, we measured the amount of carbon dioxide present in the container in which the crickets were held.  Since carbon dioxide gas is a product of cellular respiration,  the increase in CO2 over a period of time tells us the rate at which cellular respiration is occurring.
