NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.
Instead, we’ll be focusing on two compounds, FADH2 and NADH, and how they are incorporated into respiration. What Are FADH2 and NADH? Flavin adenine dinucleotide, or FADH2, is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain.
At various chemical reactions, the NAD+ picks up an electron from glucose, at which point it becomes NADH. Then NADH, along with another molecule flavin adenine dinucleotide (FADH2) will ultimately transport the electrons to the mitochondria, where the cell can harvest energy stored in the electrons.
During the citric acid cycle, six electrons are harvested as NADH, and acetyl-CoA is regenerated, hence the ’cycle’ part of the citric acid cycle. FADH2 is also made. FADH2 carries an extra electron, allowing it to make more energy per molecule than NADH. Oxidative phosphorylation is the end step for NADH and FADH2.
###
What are NADH and FADH2 ultimately used for?
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.
Where is NADH used?
NADH is used in the electron transport chain to provide energetic electrons.
Why are NADH and FADH2 important in cellular respiration?
NADH and FADH2 give their electrons to proteins in the electron transport chain, which ultimately pump hydrogen ions into the intermembrane space. This chemical gradient is used to create ATP using ATP synthase.
Which part of cellular respiration uses NADH and FADH2?
The Electron Transport Chain Stage three of cellular respiration is the use of NADH and FADH2 to generate ATP.
What is the role of oxygen in the electron?

What process converts glucose to pyruvate?
Glycolysis is the process by which glucose is broken down within the cytoplasm of a cell to form pyruvate. Under aerobic conditions, pyruvate can diffuse into mitochondria, where it enters the citric acid cycle and generates reducing equivalents in the form of NADH and FADH2.
Which process and where does it take place when glucose is oxidized to two molecules each of pyruvate ATP and NADH?
During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation.
What stage of glycolysis do two pyruvates form?
Results of Glycolysis Energy is needed at the start of glycolysis to split the glucose molecule into two pyruvate molecules. These two molecules go on to stage II of cellular respiration. The energy to split glucose is provided by two molecules of ATP.
