g 1 molecule of glucose is catabolized to pyruvate and then acetyl-coA. All the acetyl-coA enters the citric acid cycle. How many molecules of NADH are produced from the citric acid cycle only (do not include NADH from glycolysis or the pyruvate dehydrogenase complex in your calculation.) You must answer as a number i. e if you think the answer is 12, you must enter 12, not twelve.

6NADH

Explanation:

In the kreb's cycle NAD is  reduced during the reduction of 6-carbon citrate to 5 carbon Alpha-Ketoglularate.

The second is produced during the conversion of 5carbon alpha ketoglutarate to succinate. Lastly in  the conversion of fumirate  to oxoloacetate;another NADH  is formed.

However, since two pyruvate enters the Kreb's cycle therefore 6NADH(three NADH per cycle of Citric)  are produced for each molecule of glucose that is broken down from glycolysis.

Remember,each glucose molecule goes through 2 cycles of Kreb.

Futhermore co-enzyme FADH2 are also produced,with 2 molecules per 1 glucose.

These Co-ezymes transfer hydrogen ions,into the matrix of the mitochondria,where is is splits to protons and  electrons.

The electrons formed the ETC,which produce PMF  for transporting protons into the intramembranes for electrochemical gradients needed to generate energy for ATP s synthesis,by ATP synthase.
