Cellular Respiration Carbohydrates are a major source of energy for most organisms. Before the energy in carbohydrates can be used by cells the carbohydrates are broken down into simple sugars such as glucose. The energy in glucose can not be used directly by cells, so it must be transferred to a molecule called ATP. The process by which glucose is broken down to release energy is cellular respiration. Cellular respiration is a series of chemical reactions which produces ATP. This diagram shows the cycle of making and breaking down ATP. This occurs very rapidly and 10 million new ATP molecules are made in each cell every second.

Explain the three stages of cellular respiration using this diagram for extra credit.
