NADH and FADH2 made in the citric acid cycle (in the mitochondrial matrix) deposit their electrons into the electron transport chain at complexes I and II, respectively. This step regenerates NAD+ and FAD (the oxidized carriers) for use in the citric acid cycle.Click to see full answer. Hereof, what are NADH and fadh2 and what are they used for?Functions. FADH2 and NADH are created from FAD and NAD+ through reduction-oxidation reactions in the Krebs cycle during respiration as seen below: As they are shuttled away, these two compounds are used to move electrons into the electron transport chain, the final stage of respiration.Additionally, what is the difference between fadh2 and NADH? Both the NAD and FAD are both electron carriers. Main difference seen between the two is in accepting the hydrogen atoms. Hence their reduced forms are written as (NADH + H+) and FADH2. NAD is reduced to NADH in CItric Acid Cycle and glycolysis,it then transfers electrons into electron transport chain at Complex 1. Moreover, where do NADH and fadh2 drop off electrons? It takes place in the folds of the inner membrane of the mitochondria. These folds are called cristae. In this step of cellular respiration, electron carriers NADH and FADH2 drop off the electrons they’ve carried from the citric acid cycle. This drop-off allows a large amount of ATP to form.Where is NADH used?As stateted above, NADH is produced in catabolic reactions and is later used in the electron transport chain to obtain energy by converting NADH back to NAD+. NADPH is primarily produced in the oxidative part of the pentose phosphate pathway.
