What Are the End Products of Cellular Respiration?

The end products of cellular respiration are adenosine triphosphate, or ATP, molecules that the cell uses for a variety of processes. Cellular respiration yields 38 ATP molecules in prokaryotes and 36 ATP molecules in eukaryotes.

Cellular respiration is a method for cells to obtain the energy that is stored in food. It takes place in three stages: glycolysis, the citric acid cycle and electron transport. Some stages of the process require oxygen while some do not. Eukaryotic cells produce two fewer ATP molecules than prokaryotic cells during cellular respiration due to the passing of NADH molecules from glycolysis through the mitochondrial membrane.
