The reducing potential of NADH and FADH2 is converted to more ATP through an electron transport chain with oxygen as the “terminal electron acceptor”. Here is an accounting of ATP production by cellular respiration. During cellular respiration, most energy flows from glucose à NADH à electron transport chain à proton-motive force à ATP. Who is the longest reigning WWE Champion of all time? The electrons within FADH2 and NADH are then sent to the next portion of the cellular respiration process, the electron transport chain. Typical eukaryotic cell Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. Flavin adenine dinucleotide (FADH, FADH2) Overview of cellular respiration Here is an overview (table and following figure) of the process of storing the energy of one molecule of glucose in about 30 molecules of ATP. So in short, FADH2 and NADH are used during the electron transport chain to produce the bulk of the ATP that cellular respiration yeilds. Krebs cycle of cellular respiration. Tags: Question 6 .
