Energy is defined as the ability to do work. Cellular respiration provides energy for living organisms. So, cellular respiration is important because it provides the energy for living organisms to perform all of the other necessary functions to maintain life.
Cellular respiration is a process that takes place in cells and turns oxygen and sugars (such as glucose) into water, carbon dioxide, and energy that our body can use. This process, by the way, is the reason that we inhale oxygen and exhale carbon dioxide.
