What cycle produces NADH?

Glycolysis takes place in the cytoplasm. This breaks down the pyruvic acid to carbon dioxide. This produces 2 ATP and 6 NADH , for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria.

What does citric acid cycle produce?

Figure 17.2. Overview of the Citric Acid Cycle. The citric acid cycle oxidizes two-carbon units, producing two molecules of CO2, one molecule of GTP, and high-energy electrons in the form of NADH and FADH2.

Which enzymes in the citric acid cycle produce NADH or FADH2?

In the mitochondrial matrix, enzymes of the CAC (also known as Krebs cycle or tricarboxylic acid cycle -TCA) produce the reducing equivalents NADH and FADH2. They deliver electrons to complexes of mitochondrial electron-transport chain, which builds up a proton gradient that drives ATP production.

Where is NADH produced in the citric acid cycle?

mitochondria
Most of the electrons made available by the oxidative steps of the cycle are transferred to NAD+, forming NADH. For each acetyl group that enters the citric acid cycle, three molecules of NADH are produced. The citric acid cycle includes a series of oxidation reduction reaction in mitochondria .

How are NADH and GTP produced in the citric acid cycle?

The eight steps of the citric acid cycle are a series of redox, dehydration, hydration, and decarboxylation reactions. Each turn of the cycle forms one GTP or ATP as well as three NADH molecules and one FADH2 molecule, which will be used in further steps of cellular respiration to produce ATP for the cell.

How are NADH converted to acetyl-CoA in mitochondria?

The two pyruvate are converted to another molecule called acetyl-CoA where they enter the mitochondria for the citric acid cycle. 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.

How is the citric acid cycle like glycolysis?

Unlike glycolysis, the citric acid cycle is a closed loop: the last part of the pathway regenerates the compound used in the first step. The eight steps of the cycle are a series of redox, dehydration, hydration, and decarboxylation reactions that produce two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH2.

What happens to NADH and FADH2 in the electron transport chain?

The NADH and FADH2 molecules produced in the citric acid cycle are passed along to the final phase of cellular respiration called the electron transport chain. Here NADH and FADH2 undergo oxidative phosphorylation to generate more ATP. Berg, Jeremy M.
