Aerobic Respiration

Cellular respiration is the process of breaking biochemical energy from nutrients into adenosine triphosphate (ATP). This happens in all forms of life. Cellular respiration takes in nutrients and uses them to create ATP, a chemical which the cell uses for energy. Nutrients that are commonly used by cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent is molecular oxygen (O2). That type of cellular respiration is called aerobic respiration. The chemical energy stored in ATP can then be used to drive processes requiring energy.

In the microbe stage, cells must collect glucose and oxygen so that the mitochondria may produce ATP. This process also produces carbon dioxide (CO2) as waste.
