Cellular Respiration: Glycolysis, Citric Acid Cycle, Lactic Acid Fe...

In this video, I provide a detailed look at cellular respiration, the set of metabolic reactions and processes in cells that convert chemical energy from nutrients into adenosine triphosphate (ATP), which is considered the 'energy currency of the cell.' When oxygen is not present, fermentation can occur, resulting in waste products like lactic acid (in animals) or ethanol (in yeast and plants). Cellular respiration involves transporting electrons through an electron transport chain until the final acceptor, which is molecular oxygen. Anaerobic respiration, which uses electron acceptors other than molecular oxygen, should not be confused with fermentation
