These redox reactions release energy, which is used to form ATP. In eukaryotes, these redox reactions are carried out by a series of protein complexes within the inner membrane of the cell's mitochondria, whereas, in prokaryotes, these proteins are located in the cells' intermembrane space. The flow of electrons through the electron transport chain, from electron donors such as NADH to electron acceptors such as oxygen, is an exergonic process – it releases energy, whereas the synthesis of ATP is an endergonic process, which requires an input of energy. Oxidative phosphorylation (or OXPHOS in short) is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing energy which is used to reform ATP. In most eukaryotes, this takes place inside mitochondria. • Endergonic means absorbing energy in the form of work whereas Exergonic means releasing energy in the form of work. • Endergonic reactions are non-spontaneous and unfavorable, whereas exergonic reactions are spontaneous and favorable. 1 You can only upload photos smaller than 5 MB. 2  You can only upload videos smaller than 600MB. 3  You can only upload a photo (png, jpg, jpeg) or a video (3gp, 3gpp, mp4, mov, avi, mpg, mpeg, rm).  You can only upload a photo or a video. This enzyme uses this energy to generate ATP from adenosine diphosphate (ADP), in a phosphorylation reaction. This reaction is driven by the proton flow, which forces the rotation of a part of the enzyme; the ATP synthase is a rotary mechanical motor. 1 You can only upload files of type PNG, JPG, or JPEG. 2  You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM. 3  You can only upload photos smaller than 5 MB.
