Answer the following questions:

Cellular respiration:

• What is cellular respiration and what are its three stages? Cellular Respiration is a process in which cells produce the energy they need to survive. In this process, cells use oxygen to break down the sugar glucose and store its energy in molecules of (ATP) Adenosine Triphosphate. Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP. Cells use ATP to power virtually all of their activities; to grow, divide, replace worn out cells parts, and execute many other tasks. Essentially cellular respiration takes place in 3 parts:
