What Is Common To All Of The Oxidation Reactions In The Krebs Cycle??
What is common to all of the oxidation reactions in the Krebs cycle? They are all characterized by a loss of electrons from an organic molecule coupled to the reduction of an electron acceptor. The Krebs cycle occurs in the mitochondria.
How does oxidation occur in Krebs cycle?
In the oxidation reactions of the Krebs cycle the hydrogen atoms (or the electrons derived from them) do not react directly with oxygen but pass through a series of hydrogen or electron carriers the respiratory chain.
What are the oxidation reactions in the citric acid cycle?
Products
| Description | Reactants | Products |
|---|---|---|
| Combining the reactions occurring during the pyruvate oxidation with those occurring during the citric acid cycle the following overall pyruvate oxidation reaction is obtained: | Pyruvate ion + 4 NAD+ + FAD + GDP + Pi + 2 H2O | → 4 NADH + FADH2 + 4 H+ + GTP + 3 CO2 |
What are the most important reactions occurring in the Krebs cycle?
Citric Acid Cycle (Krebs Cycle)
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 is the overall reaction of the Krebs cycle?
The citric acid cycle also produces 2 ATP by substrate phosphorylation. The overall reaction for the citric acid cycle is:2acetylgroups+6NAD++2FAD+2ADP+2Piyields4CO2+6NADH+6H++2FADH2+2ATP.
