The combined actions of glycolysis, the pyruvate dehydrogenase reaction, and the citric acid cycle result in the loss of 24 protons and electrons from glucose. At which steps are electrons transferred to generate reduced cofactors?
Added by Emily B.
Step 1
In glycolysis, glucose is converted to two molecules of pyruvate. During this process, two molecules of NADH are generated (one for each glyceraldehyde-3-phosphate). So, 4 electrons are transferred in glycolysis. Show more…

Pyruvate is oxidized in preparation for the citric acid cycle. The oxidation of pyruvate yields acetyl $\mathrm{CoA}, \mathrm{CO}_{2}$ and $\mathrm{NADH}$.
When glucose enters glycolysis, it is converted into acetyl CoA. binds to oxaloacetic acid and forms citric acid. is oxidized to two pyruvate molecules. forms the coenzyme NAD.
