WebOxidation of a NADH molecule produces almost 3 ATP, and FADH 2 oxidation yields almost 2 ATP. Mitochondrial respiration may occur without ATP production, as long as the released protons are able to return to the matrix without passing through the ATP synthetase. WebScore: 4.6/5 (53 votes) . NADH converts back to NAD+ in a reverse reaction and the process of electron transfer is carried out with the movement of protons as H+ ions. The generation of positive charges from one side of the membrane to the other side activates a protein responsible for generating ATP which is the fuel your cells use.

WebFermentation is a specific type of heterotrophic metabolism that uses organic carbon instead of oxygen as a terminal electron acceptor. This means that these organisms do not use an electron transport chain to oxidize NADH to NAD + and therefore must have an alternative method of using this reducing power and maintaining a supply of NAD + for …
