glycolysis - Krebs cycle - electron transport chain
Explanation:
ATP is an abbreviation of Adenosine triphosphate. It is the energy currency which is stored in every cell. It is produced during the cellular respiration. Cellular respiration is a process in which substrate such as glucose is oxidised to release ATP. Cellular respiration occurs in every living cell all the time. It is completed involving the following chronological order: Glycolysis, Krebs cycle and electron transport chain. Glycolysis takes place in cytoplasm of the cell, Krebs cycle occurs in mitochondrial matrix and electron transport chain occurs in inner membrane of the mitochondria. ATP is produced during each steps.
The reason why is because for people who do not produce enough insulin (people with diabetes), it is important for them to get their insulin from medications, so these insulin-producing bacteria SAVE LIVES.
