Introduction to Respiration Breathing and respiration are two separate processes. Breathing is the process of moving air in and out of the lungs (inhalation and exhalation). Respiration is the process in all living organisms where energy, ATP, is produced in cells. ATP is adenosine triphosphate, which is a phosphorylated nucleotide with a similar structure to DNA and RNA. ATP is unable to leave the cell it was produced in. It occurs in the mitochondria, which are found in all animal cells. The ...
